Question

Find the product of the following monomial:
$pq,pqr,r$

• A. $p^2{q}^2{r}^2$
• B. $p^3{q}^{2}r$
• C. $p^2{q}^{4}r$
• D. None of these

Answer 1

The correct option is A $p^2{q}^2{r}^2$

We multiply the given monomials $pq,pqr$ and $r$ as shown below:

$pq\times pqr\times r=(p\times q)\times (p\times q\times r)\times r=(p\times p)\times (q\times q)\times (r\times r)=p^2\times q^2\times r^2=p^2{q}^2{r}^2$

Hence, the product of $pq,pqr$ and $r$ is $p^2{q}^2{r}^2$.
