### Your Input

**Find the geometric mean of $$$13$$$, $$$30$$$.**

### Solution

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 $$$\left(13\right)\cdot \left(30\right) = 390$$$.

Therefore, the geometric mean is $$$\sqrt{390}$$$.

### Answer

**The geometric mean is $$$\sqrt{390}\approx 19.748417658131499$$$A.**
