Add the powers of two similar bases that are in a multiplication sentence. For example, if you have x^3 * x^6, your answer would be x^9.
Multiply the powers that belong to a single base. The exponents will appear on the inside and outside of a set of parentheses. For instance, if you have (y^3)^2, you would multiply 3 times 2 to get y^6.
Refrain from multiplying or adding powers of two unlike bases within a multiplication sentence. For example, you cannot multiply a^2 * b^2 because "a" and "b" are dissimilar bases.
