simplify (x^{-4})^2

Solution

simplify

(x^{- 4})^{2}

Solution

\frac{1}{x ^{8}}

Solution steps

(x^{- 4})^{2}

Apply exponent rule:

(a^{b})^{c} = a^{b c},

assuming

a \geq 0

= x^{- 4 \cdot 2}

Multiply the numbers:

4 \cdot 2 = 8

= x^{- 8}

Apply exponent rule:

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

x^{- 8} = \frac{1}{x ^{8}}

= \frac{1}{x ^{8}}
