Basic Concept of Laws of Indices

A number of the form a^m where a is a real number, a is multiplied by itself m times,

The number a is called the base and the superscript m is called the index (plural indices) or exponent.

1.       a ^m x  a ⁿ =  a^{m + n}    --------------------Multiplication law

             Example:  p³   x  p²  = ( p  x  p x  p)  x  (p  x  p)  =  p ⁵

                  Or p³   x  p² =  p ^{3 + 2} =  p⁵

2.       a^m ÷ aⁿ   = a^{m - n   .... View More}
