There is an algebraic identity for such question. You want to cube of (3x1/3y). Such type is identified by (ab)^3. i.e \[a ^{3}b ^{3}3ab(ab)\] Now put the value of a=3x and b=1/3y and solve it.

see since a=3x and b=1/3y, first find the cube of both a and b i.e a^3=27x^3 and b^3=1/27y^3. Do you get it...

now calculate the value of 3a^2b i.e \[3\times(3x)^{2}\times(1/3y)\] Which is equal to \[9x ^{2}/y\]
