Question

assuming $x$ and $y$ are both positive, write the following expression in simplest radical form.
$2\sqrt{9x^4y^6}$
answer attempt 1 out of 2

Explanation:

Step1: Simplify the radical term

$\sqrt{9x^4y^6} = \sqrt{9} \cdot \sqrt{x^4} \cdot \sqrt{y^6}$

Step2: Compute each simplified radical

$\sqrt{9}=3$, $\sqrt{x^4}=x^2$, $\sqrt{y^6}=y^3$

Step3: Multiply with the leading coefficient

$2 \cdot 3x^2y^3$

Answer:

$6x^2y^3$
