[edit] In mathematics

One hundred [and] twenty five is the cube of 5. It can be expressed as a sum of two squares in two different ways, 125 = 10² + 5² = 11² + 2².

125 and 126 form a Ruth-Aaron pair under the second definition in which repeated prime factors are counted as often as they occur.

Like so many other powers of 5, it is a Friedman number in base 10 since 125 = 5^{1 + 2}.
