Question 9

Product of the following monomials $4p,-7q^3,-7pq$ is
a) $196p^2{q}^4$
b) $196p{q}^4$
c) $-196p^2{q}^4$
d) $196p^2{q}^3$

Answer 1

a) $196p^2{q}^4$
$\to$​​​​​​​Required product = $4p\times (-7q^3)\times (-7pq)$
$=4\times (-7)\times (-7)p\times q^3\times pq$ [multiplying the numerical coefficients]
$=196p^2{q}^4$ [multiplying the literal factors having same variables]
