To determine

To simplify: Each expression. Express the answer so that all exponents are positive. Whenever an exponent is 0 or negative, we assume that the base is not 0.

Answer to Problem 100AYU

$\frac{1}{x^{3}y}$

Explanation of Solution

Given:

$\frac{x^{-2}y}{x{y}^2}$

Calculation:

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