x/y=3/z
xz=3y
squaring on both sides
x²y²=9y²
9y²= x²y²
xz=3y
squaring on both sides
x²y²=9y²
9y²= x²y²

ok ur ans is right but is (1/9)x^2z^2 right ans too ?? cuz i'm getting two ans
i dont think so

I assume that you are asking (9y²) in terms of x and z
So, by (x/y)=(3/z)
y= (xz/3)
y²= (x²z²/9)
9y²= x²z²

i got 2 answers 1.9y²= x²z² and 2.9y²=(1/9)x^2z^2. Is 2nd ans correct?
