What is the geometric mean of 45 and 5?

Answer 1

First you have to set up a proprtion. 45 over x equals x over 5. Then you get x squared equals 225(45*5). Finally you have to find the square root of 225 which is 15.

Answer 2

The geometric mean of two numbers is the square root of their product. In this case, the geometric mean of 45 and 5 is the square root of (45 * 5) which equals the square root of 225. Therefore, the geometric mean of 45 and 5 is 15.

Answer 3

√5 * √45 = 2.236067977 x 6.708203932 = 15
