If X^3 * Y = 24
What is the value of (X^3 * Y^3 - X^2 * Y^2)?
A. X^2 * Y^2 = 36
B. X^3 * Y^2 = 72
For some reason OA is given as B I found it to be D
Because in B - dividing the equation with given equation in the problem we can find the value of Y and then X
In A, dividing the equation with given equation in the problem we get Y/X = 3/2. From this we get Y = 3X/2 and substitute in back in any equation we get X = 2 and can be found.
Did I make a mistake or is the OA incorrect?
