Negative exponent rule with 112/18/2023 ![]() ![]() ![]() For example, 2 -3 can be written as 1/2 3. In other words, we can convert a negative exponent to a positive one by writing the reciprocal of the given term and then we can solve it like a positive term. Negative Exponents tell us how many times we need to multiply the reciprocal of the base. Let us recall the rules for multiplying exponents with the same base and with different bases in the following figure. Therefore, each term will be solved separately. Solution: Here, the bases and the powers are different. It can be written mathematically as a n × b m = (a n) × (b m)Įxample: Multiply the expressions: 10 3 × 7 2 When the expressions with different bases and different powers are multiplied, each expression is evaluated separately and then multiplied. So, applying the rule, we will first multiply the bases, that is, 5 2 × 8 2 = (5 × 8) 2 = 40 2 = 1600Ĭonsider two expressions with different bases and powers a n and b m. Solution: Here, the bases are different but the powers are the same. It can be written mathematically as a n × b n = (a × b) n When multiplying exponents with different bases and the same powers, the bases are multiplied first. Here, the bases are a and b and the power is n. When the bases are different and the powers are the same.Ĭonsider two expressions with a different base and the same power a n and b n. Here, we have two scenarios as given below. When two numbers or variables have different bases, we can multiply the expressions by following some basic exponent rules.
