Question

Nd the Geometry meand of 4 and 15.

Answer 1

we know that

the geometric mean is the product of all the numbers in a set, with the root of how many numbers there are

so

In this problem we have two numbers

so

the geometric mean is equal to

`\begin{gathered} \sqrt[=]{4\cdot15} \\ \sqrt[]{60} \\ 2\sqrt[]{15} \end{gathered}`
