Expert Quality Education - Problem Solving Series Solution to the problem on exponents : Learn the basics of Exponents and powers (classes 8 and 9 CBSE) Exponents and powers are used for raising a number to the power of another as an equivalent of the number multiplied by itself as many times as the exponent. For example 2 "raised to the power" 2 is written as 2^2 which is 2 x 2.Review the law of exponents or indices which form the basics for handling powers in mathematics. Basic Laws of exponents or indices 1. Product rule : a m a n = a m+n (Addition of powers of same base) 2. Quotient rule : a m /a n = a m – n (difference in powers of same base) 3. Power of a power rule : (a m ) n = a mn (product of powers of same base) 4. Common power rule in product: a m b m = (ab) m 5. Common power rule in quotient : a m /b m = ( a/b ) m 6. Reciprocal rule (or negative exponent rule): a –
