Question

State whether True or False.

Multiply: $abx,-3a^{2}x$ and $7b^2{x}^3$.

The value is $-21a^3{b}^3{x}^5$.

• A. True
• B. False

Answer 1

The correct option is A True

$\left(abx\right)\times \left(3a^{2}x\right)\times \left(7b^2{x}^3\right)$
$=(-3)\left(7\right)a^{1+2}{b}^{1+2}{x}^{1+1+3}$
$=-21a^3{b}^3{x}^5$
