simplify s^{-5}*s^{-2}

Solution

simplify

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

Solution

\frac{1}{s ^{7}}

Solution steps

s^{- 5} s^{- 2}

Apply exponent rule:

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

s^{- 5} s^{- 2} = s^{- 5 - 2}

= s^{- 5 - 2}

Subtract the numbers:

- 5 - 2 = - 7

= s^{- 7}

Apply exponent rule:

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

s^{- 7} = \frac{1}{s ^{7}}

= \frac{1}{s ^{7}}
