simplify x^2y^{-2}

Solution

simplify

x^{2} y^{- 2}

Solution

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

Solution steps

x^{2} y^{- 2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

y^{- 2} = \frac{1}{y ^{2}}

= x^{2} \frac{1}{y ^{2}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{x ^{2} \cdot 1}{y ^{2}}

Apply rule:

a \cdot 1 = a

x^{2} \cdot 1 = x^{2}

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