Answer by josgarithmetic(39618) (Show Source): You can put this solution on YOUR website!
First one: z varies jointly as x to the half power and inversely as y squared.
Second one: I will not do this one for you, but it is too a variation of how z varies with x and y and shows the same proportionality constant, k. If an "independent" variable is in a numerator position, it is "jointly"; and if an independent variable is in a denominator position, it is "inversely".
