The geometric mean of a set of positive numbers is defined by the “nth root” of the “n”numbers multiplication.
![\[{\bar{X}_{g}}= \left (x_{1}*x_{2}\cdots x_{n} \right )^{1/n}=\sqrt[n]{x_{1}*x_{2}\cdots x_{n}}\]](http://informeeconomico.com.br/wp-content/ql-cache/quicklatex.com-e7c744b393f78f3386463511b75f9f27_l3.png "Rendered by QuickLaTeX.com")
