Question

Simplify the expression. Assume that variables represent nonzero numbers

(-5x^5)(4x^2)(-2x^6)

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

`\large\boxed{40x^(13)}`

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)`
