WebFeb 16, 2016 · There is an interesting way for defining powers with real exponents that just uses the logarithm and the exponential. The logarithm can be defined, for x > 0, by log x = ∫ 1 x 1 t d t and it's an easy exercise showing that, for x, y > 0 , log ( x y) = log x + log y By an easy induction, we can see that, for a nonnegative integer n and x > 0 , WebPositive numbers: Real numbers that are greater than zero.
