variation and matrices

P varies directly as the cube root of Q. Find the relation between P and Q.

It is given that S varies directly as T and inversely as the square root of U. Find the relation between S, T and U.

y varies directly as x and inversely as the square of z. Given that the constant is k,find the relation between x, y and z.

It is given that y varies directly as the square of x and inversely as the square root of z . If y = 8 when x = 4 and z = 36, 

y in terms of x and z is $$y=\frac{3x^2}{\sqrt{z}}$$  

If f varies directly as g and inversely as the square of h, and f = 20 when g = 50 and h = 5, find f when g = 18 and h = 6.
