It is also called standard index form or scientific notation. Any number in standard form is written as: A × 10ⁿ A is a number that is equal to or greater than 1 and less than 10, n is the integer power of 10 to multiply by to get the original value. For example, 300 in standard form would be 3 x 10².

What is an index form?

The index form of a number is that number written as an exponential expression, or a single number raised to another number. The exponent, or index, of an exponential expression tells us how many times to multiply the base by itself to evaluate the expression. We can use this fact to write a number in index form.
