simplify y^2*y^{-5}

Solution

simplify

y^{2} \cdot y^{- 5}

Solution

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

Solution steps

y^{2} y^{- 5}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

y^{2} y^{- 5} = y^{2 - 5}

= y^{2 - 5}

Subtract the numbers:

2 - 5 = - 3

= y^{- 3}

Apply exponent rule:

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

y^{- 3} = \frac{1}{y ^{3}}

= \frac{1}{y ^{3}}
