Simplify (-2x^4)^3

${(- 2 x^{4})}^{3}$

Step 1

Apply the product rule to $- 2 x^{4}$ .

${(- 2)}^{3} {(x^{4})}^{3}$

Step 2

Raise $- 2$ to the power of $3$ .

$- 8 {(x^{4})}^{3}$

Step 3

Multiply the exponents in ${(x^{4})}^{3}$ .

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$- 8 x^{4 \cdot 3}$

Multiply $4$ by $3$ .

$- 8 x^{12}$
