An unknown variable
71
One because if x3 = 1 then x must equal 1
Cube Volume = X3 The height would have to equal X All you would do is Volume/Height. Thus, you would get x3/X = X2
x3
-1/2*x-3/2 which is equal to -1/[2*x3/2]
It is a cubic equation in the variable x.

X3 X(X2) X2(X) and, X * X * X
Cube Volume = X3 The height would have to equal X All you would do is Volume/Height. Thus, you would get x3/X = X2

x3
x-5 * x3 = x-2 You add the powers, not multiply them.
X 3 plus x-142 plus x is an equation equal to x3+2x-142.
-1/2*x-3/2 which is equal to -1/[2*x3/2]
x3 + 8 = x3 + 23 = (x + 2)[x2 - (x)(2) + 22] = (x + 2) (x2 - 2x + 4)
