Question

Find the geometric mean between each pair of numbers.40 and 15

Answer 1

Given a N quantity of numbers, the Geometric Mean is equal to the N-th root of product of the N numbers

In this case, we have two numbers, then we need to multiply them and take square root:

`√(40\cdot15)=\sqrt[]{600}=\sqrt[]{100\cdot6}=\sqrt[]{100}\cdot\sqrt[]{6}=10\sqrt[]{6}`

The answer is:

10√6

Rounded is Approximately 24.5
