Question

can you help me with this question

Answer 1

First, since we are multiplying variables we add the exponents of like terms. 

This give you sqrt ($x^{4}y^{5} z^{5}$)

Now, square root each term placing them outside the sqrt and leave the variables with no square root inside. 

This give you the answer:

$x^{2} y^{2} \sqrt{yz}$
