Can someone show me how to simply this:

Question

(5x^3 y^-1 z^-5)^-3 (x^2 y^0 z^-6)^2

Answer 1

5x^3 y^-1 z^-5 = 5x^3 / yz^5
take the -3 power of that and you have
y^3z^15/125x^9

x^2 y^0 z^-6 = x^2/z^6
square that and you have
x^4/z^12

Now just multiply the two fractions and you have

y^3z^3 / 125x^5
