standard form

Standard form is a very important use of indices. It makes it easier to deal with very large numbers and very small numbers.

In standard form, numbers are written as a number between 1 and 10 multiplied by power 10.

For example, 500 000 written in standard form is 5 × 100 000 = 5 × 10⁵.

Likewise, 193 in standard form is 1.93 × 100 = 1.93 × 10².
