### What is a power of 10? (Definition)

A power of 10 is any number that is multiple of 10, which allows writing to be finite decimal.

— $10 ^ n$ with $n$ positive or zero integer is the number composed of the number 1 followed by $n$ zeros.

Example: 10^3 = 1000 (3 zeros)

— $10 ^ -n$ with $n$ positive integer is the number composed of the digit 1 in the nth position preceded by $n$ zeros with a dot after the first zero.

Example: 10^(-3) = 0.001 (3 zeros)
