yeah base 2. so 2^x=4/8
anonymous
  • anonymous
you mean 2^x = 4/8 uzma ^_^
anonymous
  • anonymous
2^(x) = 1/2 2^x = 2^(-1)
anonymous
  • anonymous
x=-1
anonymous
  • anonymous
awww....right, 2 is base

why? .-.
anonymous
  • anonymous
is it bad o_o
anonymous
  • anonymous
just wondering, you seem like a uni maths student, and you dont know how to explain that the answer is -1 without a calculator
anonymous
  • anonymous
lol,I'm an IT student ^_^ and I'm trying my best
anonymous
  • anonymous
I'm sorry if I wasn't able to explain this one though :(
anonymous
  • anonymous
no I dont care , just seemed a little strange
anonymous
  • anonymous
I know, it's that simple that I can't explain it, I know >_< it happens to me alot
anonymous
  • anonymous

anonymous
  • anonymous
yes it is ^_^
anonymous
  • anonymous
n u know wrong typing confuses the student :s
anonymous
  • anonymous
yep :) lol

I should have done maths degree , some of the elec engineering subjects I do are kinda hard , but maths is just maths , reckon I could have got better marks at it. Only problem is that a maths degree is kinda useless for getting a job, plus it would get boring after a while
anonymous
  • anonymous
yep, that's why I entered IT, I love maths + all sorts of sciences, but I need a good job
anonymous
  • anonymous
IT, do you have to do computer programming?, I had to do two semesters of first year programming in C, wasnt very fun and I didnt get a very good mark :|
anonymous
  • anonymous
I wanted to be an engineer
anonymous
  • anonymous
yep, but using java
anonymous
  • anonymous
fun? who said it was fun *faint* O_O
anonymous
  • anonymous
no elec wrong......m screaming
anonymous
  • anonymous
why are you screaming lol?

\[log_2 \frac{4}{8} = log_2 4 - log_2 8 = log_2 2^2 - log_2 2^3 = 2-3 = -1 \] Is another way you can solve it.
anonymous
  • anonymous
mathematician cant a good job :P
anonymous
  • anonymous
oh don't worry abt what he said or what I have said, just keep doing what you love and everything will be fine in the end ^_^
anonymous
  • anonymous
polpak >_< that's a very nice way to solve it
anonymous
  • anonymous
yea i do the same
anonymous
  • anonymous
i love mathematics
anonymous
  • anonymous
^_^ that's good, same~
anonymous
  • anonymous
I'm a CS major, so I've done C, C++, Java, and ASM ;)
anonymous
  • anonymous
I dont know, just that I wanna build stuff and be useful to society , one day many years fromnow everyone will remember me because of some great electrical invention :P
anonymous
  • anonymous
wow..good pol
anonymous
  • anonymous
wow o_o I heard C is hard, but since I'll be majoring in Computer engineering, I was told that we have to learn C
anonymous
  • anonymous
lol polpak :) that's a nice dream
anonymous
  • anonymous
Yeah, C is used a lot for embedded hardware.

i need to learn MATLAB
anonymous
  • anonymous
oh good LORD , good luck to me =_=
anonymous
  • anonymous
any expert here??
anonymous
  • anonymous
I use MATLAB in my communication lab class
anonymous
  • anonymous
^_^
anonymous
  • anonymous
maths is just maths , all it is is repetition
anonymous
  • anonymous
but still a beginner lol
anonymous
  • anonymous
oh good to hear:)
anonymous
  • anonymous
math is life, math is love, math is everything ^_^
anonymous
  • anonymous
i still need to begin...must communicate with u :P
anonymous
  • anonymous
it represents the geometry of the beautiful universe :)
anonymous
  • anonymous
no, its a tool to make things easier , its a tool , not the whole story
anonymous
  • anonymous
lol, I face difficulty in it myself >_<
anonymous
  • anonymous
lol, to me, math is everything :)
anonymous
  • anonymous
its a tool without which u cant take a start:)
anonymous
  • anonymous
every problem in life, is just like a math problem ~ something Albert Einstein has said
anonymous
  • anonymous
lol, different points of views, nice ^_^
anonymous
  • anonymous
elec...u r an engineer?
anonymous
  • anonymous
well, there was a method to my madness when I chose a username
anonymous
  • anonymous
well, there was a method to my madness when I chose a username
anonymous
  • anonymous
LOL
anonymous
  • anonymous
:D
anonymous
  • anonymous
you are an Electrical engineer!
anonymous
  • anonymous
thats y i chose my original name
anonymous
  • anonymous
|*-*| nice
anonymous
  • anonymous
what does uzma stand for?
anonymous
  • anonymous
the great ;)
anonymous
  • anonymous
nice ^_^
anonymous
  • anonymous
I believe that each and everyone of you is going to be someone great in the future, just don't remember a girl with the username sstarica =P
anonymous
  • anonymous
I mean, dont forget*
anonymous
  • anonymous
>_<...typo..is hunting me
anonymous
  • anonymous
^_^" aha
anonymous
  • anonymous
thats nice...u are a girl?
anonymous
  • anonymous
yeh prob , but a mathematician isnt as well know as any other profession
anonymous
  • anonymous
didn't I sound like one? o_o, you never know what a mathematican can do
anonymous
  • anonymous
^_^
anonymous
  • anonymous
uzma >_> you thought I was a dude this whole time?
anonymous
  • anonymous
cant do anything. They study all the stuff that engineers use to make useful stuff
anonymous
  • anonymous
no i dint think about that...who cares a girl or guy....if the forum is good, its ok
anonymous
  • anonymous
lol, I agree uzma ^_^
anonymous
  • anonymous
lol elec, every profession has its use :)
anonymous
  • anonymous
what do u guess me?:P
anonymous
  • anonymous
it would be easier for a engineer to swap with a mathematician, than it would for a mathematician to swap with an engineer. For starters engineering involves group work and gets quite stressful at times, whereas maths is all independant
anonymous
  • anonymous
mathematicans can do stuff engineers can't do , engineers can do stuff mathematicans can't do, CS majors can do stuff engineers can't do and so on ~
anonymous
  • anonymous
you're a guy uzma :)
anonymous
  • anonymous
it's like a cycle elec ^_^
anonymous
  • anonymous
:d
anonymous
  • anonymous
m a girl:p
anonymous
  • anonymous
that's why all exist together ^_^ to help each other out in different fields
anonymous
  • anonymous
LOL! I'm sorry >_< I strike again and do the same mistake all over a again!
anonymous
  • anonymous
but uzma = sounds more like a guy's name .-.
anonymous
  • anonymous
star is right.every1 has its on worth,
anonymous
  • anonymous
we all work for one goal , to make a better world ^_^
anonymous
  • anonymous
no its not even a co-name :)
anonymous
  • anonymous
lol, my dearest apologies :)
anonymous
  • anonymous
yeh but some maths is just rubbish , like some of linear algebra , and what about pure maths , whats the application to socity there :P
anonymous
  • anonymous
awww np :)
anonymous
  • anonymous
:) someday, you'll face a problem that not only a mathematican can solve it for you. You will understand later
anonymous
  • anonymous
look elec..this is our own perception, how do we take things
anonymous
  • anonymous
all you really need is calculus , rest is BS
anonymous
  • anonymous
lol uzma calm down ^_^
anonymous
  • anonymous
i m...dont worry about me:)
anonymous
  • anonymous
not really, how can you understand calculus without knowing the basics in the first place?
anonymous
  • anonymous
are you telling me you became great in calculus without taking the 1, 2 3's in school? :)
anonymous
  • anonymous
or 1 x 1? 3x + z?
anonymous
  • anonymous
Number theory was widely regarded as a toy that no one would ever be able to find a use for any practical purpose. Now the entirety of our electronic security infrastructure is based on its precepts.
anonymous
  • anonymous
good show pol..we can find the application of other fields like wise:)
anonymous
  • anonymous
stages, we all took stages in life just like in math
anonymous
  • anonymous
yep ^_^
anonymous
  • anonymous
networking is based on topology....another pure maths which sucks u
anonymous
  • anonymous
yeh, but as an elec engineer ill prob learn bout that stuff, and its application. but just doing tons of maths without being able to sit down and build something of use is well , pointless
anonymous
  • anonymous
its easy to come n easy to go :p
anonymous
  • anonymous
networking is also based on linear algebra.
anonymous
  • anonymous
lol :) you cannot build anything without accurate measurements :)
anonymous
  • anonymous
u cant even cook or urself without measurement :p
anonymous
  • anonymous
lol, that's more to chemistry ;D
anonymous
  • anonymous
for*
anonymous
  • anonymous
maths too star
anonymous
  • anonymous
it's funny though, I still can't cook >_< ;D
anonymous
  • anonymous
yes it's true! Lol
anonymous
  • anonymous
oh great me too ;)
anonymous
  • anonymous
but I exceed you with one point uzma, I can cook eggs LOL
anonymous
  • anonymous
m 1 step ahead.i can cook chicken ;)
anonymous
  • anonymous
uyeh, but you dont need a maths degree to deal with ratios on a recipe :p see what I am talking about , most of the practical ( and therefore , useful ) maths is taught in high school and first or second year maths ( the stuff that engineers do ). Higher maths is sorta useless
anonymous
  • anonymous
>_> we're equal
anonymous
  • anonymous
not really, higher math = deals with advanced problems ^_^
anonymous
  • anonymous
it's not abt a math degree elec, it's about learning and wanting to learn more :)
anonymous
  • anonymous
and how to apply the things you learn in what you do everyday ^_^
anonymous
  • anonymous
that's all~
anonymous
  • anonymous
yup ..thats all.congrats star we won ;):D
anonymous
  • anonymous
lol, there was a war here? o_o oh my, I didn't mean it that way
anonymous
  • anonymous
so here's a medal for u too :p
anonymous
  • anonymous
kidding just kidding :D
anonymous
  • anonymous
I already gave you all a mdeal for trying to solve the question lol and thank you ^_^
anonymous
  • anonymous
>_>
anonymous
  • anonymous
otherwise we r all frends :)
anonymous
  • anonymous
yep ^_^ lol
