Question

Product of $4p,-7q^3,-7pq$ is ____.

• A. $196p^2{q}^4$
• B. $-196p^2{q}^4$
• C. $49p^2{q}^4$
• D. $206p^2{q}^4$

Answer 1

The correct option is A $196p^2{q}^4$

Given monomials are,
$4p,-7q^3,-7pq$
Product $=4p\times -7q^3\times -7pq$
$=[4\times (-7)\times (-7\left)\right]\times (p\times p)\times (q^3\times q)$
$=196\times p^2\times q^4$
$=196p^2{q}^4$
