Index form is where a number is expressed using exponents - one number to the power of another.
For example, 2 x 2 x 2 x 2 x 2 is the same as 2 to the power of 5, written as 2^5. If you square a number, you write a small 2 above the number, and that is (the number)x(the number). So, it is there twice. If it was 2 x 2 x 2 x 2 x 2 there are five twos in the product, so it's 2 to the power of 5.

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.
