Geometric Mean of Growth Factors

Problem

For a sequence of growth factors g_i (for example 1.1 for ten percent growth), the compound average factor is the geometric mean (product_i g_i)^(1/n).

Given the growth factors, return the geometric mean.

Hint

Multiply all factors together and take the n-th root.
