Standard index form is a convenient way to represent very large or very small numbers. It is often used in physics where these extreme values are used regularly.
E.g.
6.63 x 10-34 is a common value used.
5 x 102 is 500
which is equivalent to 5 x 10 x 10
5 x 10-2 is 0.05
which is equivalent to 5 / 10 / 10

Are index form and standard form the same thing?
No. In the index form a number is expressed as a multiple of its prime factors whereas in the standard form it is expressed as a number between in the range [1, 10) multiplied by an integer power of 10. So, for example, 1728 in index form = 26*33 1728 in standard form = 1.728*103 The index form can only be used for integers.
