Answer 1

A. 3x /3ysqrtof2. Multiply numerator and denominator by sqrt of 2
Then you have 3xsqrt of 2 /. 6y reduce by 3 both numerator and denominator
You have x sqrt of 2 / 2y

Answer 2

`\large\begin{array}{I} \mathtt{ ( √(9x^2))/( √(18y^2))= (3x)/( 3√(2)y)= (x)/( √(2)y)}= ( √(2)x)/(2y) \end{array}`

Answer is A
