Answer 1

CORRECT QUESTION :–

Simplify the expression => p²qr+pq²r+pqr² for p=1 and r =5

ANSWER :–

GIVEN :–

● P = 1 , r = 5

● expression p²qr + pq²r + pqr²

SOLUTION :–

$\\ { \bold{ = {p}^{2} qr + p {q}^{2} r + pq {r}^{2} }} \\ \\ \\ { \bold{ \: \: \: \: \: \: . \: \: now \: \: put \: \: the \: \: values - }} \\ \\ \\ { \bold{ = {(1)}^{2} q(5) + (1) {q}^{2}(5) + (1)q( {5)}^{2} }} \\ \\ \\ { \bold{ = 5q + 5 {q}^{2} + 25q }} \\ \\ \\ { \bold{ = 5 {q}^{2} + 30q}} \\ \\ \\ { \bold{ = (5q)(q + 6)}}$
