# Math Help - Exponent Laws

1. ## Exponent Laws

Hi there,

here is a question with a negative exponent on the bottom. I would appreciate ANY!! help!

Simplify.

x^2a-h x x^a-3h / (x^3a+h) ^-2

THANK YOU!
^ means exponent

You have,
$\frac{x^2 a-hx x^a-3h}{(x^3a+h)^{-2}}$
Since you are dividing by a negative exponent you can bring the denominator to the numerator and remove the negative,
$(x^2a-hx x^a-3h)(x^2a+h)^2$

Are you saying: $\frac{x^{2a-h}\times x^{a-3h}}{\left(x^{3a+h}\right)^{-2}}$

or: $\frac{\left(x^{2a}-h\right)\times \left(x^{a}-3h\right)}{\left(x^{3a}+h\right)^{-2}}$

if it's neither of those two than try rewriting it with as many paranthesis as possible and write out the word "times".
