Question

Question Determine the geometric mean of 54 and 18. Round your answer to then nearest tenths place ifnecessary.

Answer 1

We have the following:

$x=\sqrt[n]{x_1\cdot x_2\ldots x_n}$

replacing:

$\begin{gathered} x=\sqrt[2]{54\cdot18} \\ x=\sqrt[2]{972} \\ x=18\sqrt[]{3}=31.18 \end{gathered}$

the geometric mean of 54 and 18 is 31.18
