is this meaning that theese are all in exponent form?? Like its saying -2x to the 2y power?? Just answer that then i will know how to do[/quote]emmaiskool242 said:(-2x^2y^-3)^-2

It means 2(x^2)

It works the same, negative or positive. I'll split it up {} each term.

({-2}{x^2}{y^-3})^-2 =

{(-2^1)^-2}*{(x^2)^-2}*{(y^-3)^-2} =

{-2^(1*-2)}*{x^(2*-2)}*{y^(-3*-2)} =

{-2^-2}*{x^-4}*{y^6} = (if you want)

y^6/(2^2*x^4)

You change the sign of the exponent when you move it across the /

Try again as

({-2}{a^3}{x^-3})^-3 and

({2^1}{x^1}{y^-2}*{x^2}{y^-1})^-1
