Rule 1: If a constant or variable has index as '0', then the result will be equal to one, regardless of any base value. a0 = 1 Example: 5 0 = 1, 12 0 = 1, y 0 = 1 Rule 2: If the index is a negative value, then it can be shown as the reciprocal of the positive index raised to the same variable. a-p = 1/ap Example: 5 -1 = ⅕, 8 -3 =1/8 3

is the base and 5 is the index. Also, 10 × 10 × 10 × 10 = 10 4 And, × × = = 10 3 Generally, in a n = a × a × a × × a a multiplied by itself n times a is the base and n is the index or power. Therefore, a n is in index form, where a 0. Laws of indices To do calculations with indices we follow certain rules. These rules are called the.

Some basic rules of Indices that you must remember are: Rule #1: When we multiply two numbers which have the same base, we add their powers. Rule #2: When we divide two number which have the same base, we subtract their powers. Rule #3: When we have a power to the power of something else, we multiply the powers together.

The exponent laws, also called the laws of indices (Higgens 1998) or power rules (Derbyshire 2004, p. 65), are the rules governing the combination of exponents (powers). The laws are given by x^m·x^n = x^(m+n) (1) (x^m)/(x^n) = x^(m-n) (2) (x^m)^n = x^(mn) (3) (xy)^m = x^my^m (4) (x/y)^n = (x^n)/(y^n) (5) x^(-n) = 1/(x^n) (6) (x/y)^(-n) = (y/x)^n, (7) where quantities in the denominator are.
