Solve and Simplify

$(\frac{x^{-\frac{2}{3}}y^\frac{3}{4}}{x^\frac{1}{2}})^{-4} =$

First i would change it too: $\frac{1}{(\frac{x^{-\frac{2}{3}}y^\frac{3}{4}}{x^\frac{1}{2}})^{4}} =$

Is that correct? I need some more guidance.

Thanks.

its a sensible first step, i'd simplify the x's inside the bracket next

$\frac{x^{\frac{-2}{3}}}{x^{0.5}} = x^{\frac{-2}{3}-0.5} = x^{\frac{-7}{6}}$

Oh okay thanks. so $<br /> \frac{1}{(\frac{y^{\frac{3}{4}}}{x^{\frac{-7}{6}}})^4}<br />$

Whats next?

Hi hydride,
multiply exponents and simplify

each term of the numerator and denominator must be raised to -4.answer will be of in termof x to a power andy to a power
example (x^2)^1/2=x 2x1/2=1 thats 2 times 1/2=1
