Question

Find the product

$\left(-\frac{10}{3}p{q}^3\right)\times \left(\frac{6}{5}{p}^{3}q\right)$

• A. $-4p^3{q}^3$
• B. $4p^3{q}^3$
• C. $p^4{q}^4$
• D. $-4p^4{q}^4$

Answer 1

The correct option is D $-4p^4{q}^4$

$\left(-\frac{10}{3}p{q}^3\right)\times \left(\frac{6}{5}{p}^{3}q\right)$
$=(-\frac{10}{3})\times \left(\frac{6}{5}\right)\left(p^{3}q\right)\times \left(p{q}^3\right)$
$=-4p^4{q}^4$
