The geometric mean of 25 and 100 is 50.0
The geometric mean of 9 and 25 is: 15.0
15 is the geometric mean of 25 and 35.
geometric mean of 4 and 25=√(4x25)=√100=10
Geometric mean of 2 and 25 = sqrt(2*25) = 5*sqrt(2) = 7.071
25
The geometric mean of two numbers is the square root of their product. In this case, the geometric mean of 5 and 25 would be the square root of (5 * 25) which equals the square root of 125. Simplifying further, the square root of 125 is approximately 11.18. Therefore, the geometric mean of 5 and 25 is approximately 11.18.
