1. ## Algebra Questions - Simple but driving me crazy

Hey guys,

Couple of questions i'm getting hung up on.... i know one of you guys will know the answers. I uploaded an attachment... hope thats easy enough.. if not let me know and i will figure out some other way to post the problems.

Thanks,

DEMPC

BTW... is there an easy tool (calculator, etc) for typing in a math problem instead of saving it as an attachment?

Hi dempc,

$\left(\frac{a^{-3}b^7}{c^{-1}}\right)^4=\left(\frac{b^7c}{a^3}\right)^4=\frac {b^{28}c^4}{a^{12}}$

$\frac{5-x}{2x-10}=\frac{-(x-5)}{2(x-5)}=-\frac{1}{2}$

$\frac{1}{2x^2}+\frac{1}{x^2y}=\frac{y+2}{2x^2y}$

See http://www.mathhelpforum.com/math-help/latex-help/ and look at the first post for a PDF on how to use latex.

Will post again if i run into any other problems.

Thanks again,

4. ## one more for you

i came up with 3(x+3)/x+9 but i'm thinking it may just be 2
