C 13 28 INDICES (Chapter 2) These examples can be generalised to the following index laws: If the bases a and b are both positive, and the indices m and n are integers, then: am xan = am+n am an = am-n (am)n = amn (ab)n = anfn a n an (7) ª = bn aº = 1, a 0 1 a-n = an = | To multiply numbers with the same base, keep the base and add the indices. To divide numbers with the same base, keep the base and subtract the indices. When raising a power to a power, keep the base and multiply the indices. The power of a product is the product of the powers. The power of a quotient is the quotient of the powers. Any non-zero number raised to the power of zero is 1. 1 and in particular a-1 Example & Hio
