Question

Use the rules of exponents to evaluate and simplify the following expression. Type all without negative exponents. Do not distribute the exponent in the answer.
(x y) ^-3 =

is it 1/(xy)?

This leads to 1/(xy)^3.

You see, going from the top to the bottom alters the sign of the exponent to its opposite.

ANSWER: 1/(x^3•y^3)
