How to Rewrite a Number in Expanded Form With Exponents

Rewriting a Number in Expanded Form

Expanded form represents a number expanded into an addition statement. Rewriting a number in its expanded form with exponents helps you to better understand scientific notation. When determining what exponent to use for a power of ten, look at how many zeroes you have. For example, if the number is 1,000, which has three zeroes, it is 10 to the third power. In the example below, 213 is rewritten in expanded form.
