how do i find the geomtric mean of 9;5;6;10;5?

$${\left({\mathtt{9}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{5}}\right)}^{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)} = {\mathtt{6.699\: \!875\: \!826\: \!622\: \!859\: \!3}}$$

.
