Question

d. which of the following expressions has a value equivalent to $\frac{x^{2}}{y^{2}}$? select all that apply. $\frac{x^{2}y^{3}}{x^{4}y}$ $x^{2}y^{-2}$ $(x^{-2}y^{2})$ $\frac{x^{9}cdot y}{x^{7}y^{3}}$ points possible: 2 unlimited attempts.

Explanation:

Step1: Simplify first expression

$\frac{x^{2}y^{3}}{x^{4}y}=\frac{y^{2}}{x^{2}}$

Step2: Simplify second expression

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

Step3: Simplify third expression

$(x^{-2}y^{2})=\frac{y^{2}}{x^{2}}$

Step4: Simplify fourth expression

$\frac{x^{9}\cdot y}{x^{7}y^{3}}=\frac{x^{2}}{y^{2}}$

Answer:

$x^{2}y^{-2},\frac{x^{9}\cdot y}{x^{7}y^{3}}$
