WebbLaws of indices provide us with rules for simplifying calculations or expressions involving powers of the same base. This means that the larger number or letter must be the same. For example, 25 ×23 = 28 2 5 × 2 3 = 2 8 x10 ÷x4 = 106 x 10 ÷ x 4 = 10 6 We cannot use laws of indices to evaluate calculations when the bases are different For example, WebbThis video explains how to simplify equations involving indices, and goes over a few examples.My videos cover the O Level Additional Mathematics Exam syllabu...

The index can take any value. The index laws simplify the process of simplifying indices. For example, the multiplication law: a ² x b ³ = a x a x a x a x a = a ^5. ------- --------------. chrome pdf 转 图片
