(x-3)/4 = 10
Multiply each side by 4:
x - 3 = 40
Add 3 to each side:
x = 43

x5 = x3 times x2. In this case x3 = 64 so x = cube root of 64 ie 4
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.

10/x3 = 10 x-3d/dx(10x-3) = -30 x-4 = -30/x4
