If you have like terms then to multiply you add the exponents and to divide you subtract.

So, x2 * x3 = x5 and y7 / y5 = y2

Also, for example, 2x2 * x3 = 2x5 (we can do this as the terms are like; x's only)

But if you do not have like terms then this does not apply.

For example, x2 * y3 does not equal xy5.
