You’ll learn how to multiply indices, divide indices, use brackets and indices, how to raise values to the power of 0 and to the power of 1, as well as fractional and negative indices. Look out for the index laws worksheet and exam questions at the end.

Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. Try it yourself: So an Exponent saves us writing out lots of multiplies! Example: a7. Notice how we wrote the letters together to mean multiply? We will do that a lot here.

We will look at each law of indices formula with index laws examples one by one for various algebraic indices. Laws of Indices Formulas. Given below are all the laws of indices that you will encounter while dealing with indices. No matter how complex the problem is, these are all the fundamental laws that govern the indices rules. Multiplication

We will discuss here about the different Laws of Indices. If a, b are real numbers (>0, ≠ 1) and m, n are real numbers, following properties hold true. (i) a m × a n = a m + n. (ii) a -m = 1 am 1 a m. (iii) am an a m a n = a m – n = 1 am−n 1 a m − n. (iv) (a m) n = a mn. (v) (ab) n = a n ∙ b n. (vi) a 0 = 1. (vii) if a m = a n then m = n.
