Question

Simplify the expression. Assume that variables represent nonzero numbers

Answer 1

$\bf (-5x^5)(4x^2)(-2x^6)\implies (-5)(-2)(4)x^5x^2x^6\implies 40x^{5+2+6}\implies 40x^{13}$

Answer 2

Answer:

$\large\boxed{40x^{13}}$

Step-by-step explanation:

$(-5x^5)(4x^2)(-2x^6)=\bigg((-5)(4)(-2)\bigg)(x^5x^2x^6)\\\\\text{use}\ a^na^m=a^{n+m}\\\\=40x^{5+2+6}=40x^{13}$
