Question

If m=2 and n=1, then find the value of following polynomials:
$4m^{2}n$

• A. 16
• B. 14
• C. 13
• D. None of these

Answer 1

The correct option is A 16

Let us substitute $m=2$ and $n=1$ in the given polynomial $4m^{2}n$ as shown below:

$4m^{2}n=4(2{)}^{2}1=4\times 4=16$

Hence, $4m^{2}n=16$, if $m=2$ and $n=1$.
