This step shows combining exponents for terms that have the same base. Example: 2x can NOT be combined with 4x2 Why not? Preview this quiz on Quizizz. 20y^2+6y^2 = 26y^2. So in this case, we will add the 3, 5 and 9 that is in front of the x terms. There are several other rules that go along with the power rule, such as the product-to-powers rule and the quotient-to-powers rule. For example. Exponents: Division rule a x a y = a (x â y) {a^x \over a^y}=a^{(x-y)} a y a x = a (x â y) 17. Combining the exponent rules. When you combine like terms, be sure to use the + or - that is in front of the coefficient, or number in before the letter. This step is the final simplification of what is inside the parentheses.
