Answer:
This is incomplete. What do you need to find? There's not enough information to figure out what to do.
Step-by-step explanation:
![\sqrt{9x^2} / \sqrt{18y^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B9x%5E2%7D%20%2F%20%5Csqrt%7B18y%5E2%7D%20)
after taking sqrt both side
3x/
![\sqrt{9*2y^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B9%2A2y%5E2%7D%20)
3x/3y√2
x/√2y
multiply both denomenator and numerator by√2
√2x/2y
Answer is A
I’m not sure how to explain it but the answer is B
