Question

Solve the polynomial: $\sqrt{169m^8{n}^6(l-m{)}^4}$

• A. $\left|m^2{n}^3\right(l-m{)}^2|$
• B. $13\left|m^4{n}^3\right(l-m{)}^2|$
• C. $13\left|m^2{n}^3\right(l-m\left)\right|$
• D. $\left|13m^2{n}^3\right(l-m{)}^2|$

Answer 1

The correct option is B $13\left|m^4{n}^3\right(l-m{)}^2|$

$\sqrt{169m^8{n}^6(l-m{)}^4}$
$=$ $\sqrt{\left(13m^4{n}^3\right(l-m{)}^2{)}^2}$
$=$ $13\left|m^4{n}^3\right(l-m{)}^2|$
