Laws of Indices

Laws of indices. Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full

For real numbers m,n and valid bases a,b, the following basic laws hold –

Law 1

Note that for this law to be applicable, the bases of both of the numbers to be multiplied must be the same.

Law 2

Important Result –

For applying the above Law, if we choose both m = 1 and n = 1, then we get –

This is a very important result and we’ll use it often to simplify our algebraic expressions involving indices.

Law 3

Example –

Law 4

The four laws mentioned above are sufficient for evaluating any arbitrary expression involving indices.
