Really need some help with my maths homework, any help would be greatly appreciated

by the way "-²" is to the power of negative 2, same deal with negative 3.

^ is just to the power of.

These ones have to go to positive indicies, thats all:

(c-²)/4

(3x^-1 y-²)/z²

(x-³)/(3^-1)

(P^½)-½

(2x-³)³

thanks

(c-²)/4 = 1/4c²

(3x^-1 y-²)/z² = 3/xy²z²

(x-³)/(3^-1) = 3/x³

(P^½)-½ = p^(-1/4)=1/p^(1/4)

(2x-³)³ = 2x^(-9)=2/(x^9)
