or something much more involved?

- anonymous

that is what i was wondering what grade are you in lauren and what type of math course are you taking?

- anonymous

the ------ is a divided by sign. and the 2's above the numbers are exponents. i need it simplified.

- anonymous

Idk if i can help you then i am a sophomore in high school but i am pretty sure it is 2, but im probably wrong :P

- anonymous

ah.. so this can be written as:
(3-2-(-5)^2)/(2^2-(-4)^2) where "^" represents exponentiation?

- anonymous

yep. that is right. now can u help me solve it?? lol

- anonymous

yes.. do u want step by step?

- anonymous

Well i dont really need it. but i would like an answer if possible.

- anonymous

what answer did u get for that?

- anonymous

i havent done that one yet. i dont really know where to start.

- anonymous

cross multiply??

- anonymous

first put them over the same denominator so u can combine them

- anonymous

multiply the top and bottom of the first fraction by 5

- anonymous

multiply the top and bottom of the second fraction by 7

- anonymous

k did that

- anonymous

the 2 denominators do not have the same sign. one is positive. one is neg. is that ok?

- anonymous

-25/35 - 42/-35

- anonymous

notice that a negative in the denominator still make the right fraction a negative number... so u have a negative times a negative which makes a positive

- anonymous

ohh ok

- anonymous

if it was addition would it stay negative though?

- anonymous

yes

- anonymous

ok now what

- anonymous

-25 - 42 ?

- anonymous

-67/35 is that the answer?

- anonymous

since they now have the same denominator u can combine them... i get 17/35

- anonymous

-25/35 - 42/35

- anonymous

but -25 - 42 is -67...

- anonymous

the second fraction becomes positive because of the double negative

- anonymous

k i got it.

- anonymous

Fun.. did u get the same answer?

- anonymous

Yes! u were right! :) can u help me with this one? i have 2 more of these.
