the example says this:
Use the substitution zy=x to express
x to the 5 / z to the 3y to the 3 as a power of x.
Using laws of exponents, we obtain
xto the 5/ z to the 3y to the 3= x to the 5/ (zy) to the 3
If we then use the substitution zy=x we have
x to the 5/(zy) to the 3= x to the 5/ x to the 3
that equals= x to the 2. howd they get the 2?
heres the question im stuck on
x to the 7y to the 7/z, z=xy
