simplify x^{-7}*x^3

Solution

simplify

x^{- 7} \cdot x^{3}

Solution

\frac{1}{x ^{4}}

Solution steps

x^{- 7} x^{3}

Apply exponent rule:

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

x^{- 7} x^{3} = x^{- 7 + 3}

= x^{- 7 + 3}

Add/Subtract the numbers:

- 7 + 3 = - 4

= x^{- 4}

Apply exponent rule:

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

x^{- 4} = \frac{1}{x ^{4}}

= \frac{1}{x ^{4}}
