Answer 1

Answer:

A

Step-by-step explanation:

Numerator

(3x)(3x) = 9x^2

√9x^2 = 3x

Numerator = 3x

Denominator

√18y^2 = √18 · √y^2

√18 = 3√2

√y^2 = y

3√2y

Denominator = 3√2y

Now we need to rationalize the denominator, and get rid of the square root on the bottom

$\frac{3x}{3\sqrt{2} y}$ * $\frac{3\sqrt{2} }{3\sqrt{2}}$ = $\frac{6x\sqrt{2} }{12y}$ = $\frac{x\sqrt{2} }{2y}$
