SOLUTION: Write an equation describing the relationship of the given variables. y varies jointly as the square of x, the cube of z, and the square root of w. When x = 4, z = 2, and w = 9, t

Question 1128290: Write an equation describing the relationship of the given variables.
y varies jointly as the square of x, the cube of z, and the square root of w. When x = 4, z = 2, and w = 9, then y = 384.
*Following another�s advice of subsuiting each Constant into the corresponding variable place, my answers are still incorrect. My answer so far have been y= x^2� z^3� sqrt(w). y= 4^2� 2^3� sqrt (9).
Y= 384/ 4^2�2^3� sqrt(9). Can someone explain what I am doing incorrect in setting up the above equation.

The fact that varies jointly as and the and sqrt(w) means that
for some constant
When , , and , then

so, describing the relationship of the given variables
