Geometric mean of $$$10$$$, $$$15$$$

Find the geometric mean of $$$10$$$, $$$15$$$.

The geometric mean of data is given by the formula $$$\left(\prod_{i=1}^{n} x_{i}\right)^{\frac{1}{n}}$$$, where $$$n$$$ is the number of values and $$$x_i, i=\overline{1..n}$$$ are the values themselves.

Since we have $$$2$$$ points, $$$n = 2$$$.

The product of the values is $$$\left(10\right)\cdot \left(15\right) = 150$$$.

Therefore, the geometric mean is $$$\sqrt{150} = 5 \sqrt{6}$$$.

The geometric mean is $$$5 \sqrt{6}\approx 12.24744871391589$$$A.
