For numbers 5 and 20 the value of the geometric mean of these numbers is
Gm (5, 20) = 10
The definition of geometric mean is a calculation that is performed on a set of numbers which consists of calculating the square root of the product between them, the equation is as follows:
Gm (a,b) = √ab
Then in our case that we have the values 40 and 15, these are equivalent to the variables a and b
We substitute and solve for the square root
