Okay. sooo, this is really broad, but I don't understand negative exponents.... At all.

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
So you got some specific questions or do you want me or us to explain you negative exponents from scratch?

MetalPenBest ResponseYou've already chosen the best response.0
Ummmmmmm. Why does a negative exponent make a fraction? I don't understand the basic concept.
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
Negative exponents simply means this: \[a^{x} = {1 \over a^x}\]
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
yea slaaibak got it
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
Yes but why are they defined that way?
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
do you know \[a^x \times a^y= a^{x+y}\]
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
now say we want \[a^x \times a^y = 1\]
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
You'd made one negative!!! AHHH I GET IT!
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
so when we solve that we get \[a^{x+y}= 1 = a^0\]

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
thats good! You get it :D

Teehee! Wow that just clicked. My math teacher didn't explain it that way.......

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
its my pleasure helping you click it :D

So another thing, how do you deal with #s with exponents in a fraction?
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
Give an example please?

MetalPenBest ResponseYou've already chosen the best response.0
Ummmm. How do you make fractions with this equation thing?
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
3 over 4 \[3 \over 4\]
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
Use this code: {1 over 2} would be \[{1 \over 2}\]
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
... Um can I just say it?
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
yea what is your doubt? i do not comprehend it

MetalPenBest ResponseYou've already chosen the best response.0
Okay so if you had y^5 times 2^3 over y^4 times x^2.
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
Or something to that effect.
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
\[ y^5 \times 2^3 \over y^4 \times x^2.\]
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
\[{ y^{5} * 2^3 \over y^4 * x^2}\]
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
is that your query?
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
You're faster than me xD
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
If there's multiplication, you can take y^5 and but it below the line, \[y^{5} = {1 \over y^5}\] You can immediately write 2^3 as 8. So now you have: \[{1 \over y^5} * {8 \over x^2 * y^4}\]
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
Then, you can multiply similar variables with eachother and add the powers. it becomes: \[8 \over y^9 * x^2\]

What are you talking about?
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
about the question you asked
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
I made a spelling mistake in my post.
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
Yeah but how did you get y^9?
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
I know you have to add... Or subtract the exponents or something.
 2 years ago

slaaibakBest ResponseYou've already chosen the best response.1
\[y^4 * y^5 = y^{5 + 4}\]
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
the main aim of such questions is to convert your negative exponents into positive by taking its reciprocal
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
Um one more thing. How would you get {1 over 9} % of 90. Or something like that.
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
Aw shoot. I messed up the thing.
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
percent is always divided by 100
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
so 1/9 percent is \[(1/9 ) \over 100 = 1\over900\]
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
of 90 is 1/900 of 90.. of implies multiplication
 2 years ago

Akshay_BudhkarBest ResponseYou've already chosen the best response.5
so it is 1/900 times 90 = 90/900 = 1/10
 2 years ago

MetalPenBest ResponseYou've already chosen the best response.0
That makes sense! Okay that's all! And I have to go. Thank you so much. ^.^
