Question

The geometric mean of 9 and 15

Answer 1

Answer:

$\sqrt{135\\}$

Step-by-step explanation:

Geometric mean can be calculated like such:

a/x = x/b

Where a and b are your 2 numbers. By solving for x by cross-multiplying you get:

x^2=ab

So to solve for geometric mean, all you have to do is to multiply the two numbers and take the square root:

9(15)=135

$\sqrt{135\\}$

Answer 2

The geometric mean of 9 and 15 is 11.62

Given two integers A and B, the geometric mean of the integers is expressed as:

GM = √A×B

Given the values 9 and 15, the geometric mean of the values is expressed as:

GM = √9×15

GM = √135

GM = 11.62

Hence the geometric mean of 9 and 15 is 11.62
