To calculate the geometric mean multiply the numbers together and take the nth root (where n is the number of numbers). geometric mean of 8 & 7 is: √(8 x 7) = √56 ~= 7.48
7.9373 (rounded)
sq root (6 X 7) = about 6.48.
GM(7, 25) = sqrt(7*25) = 13.23 approx.
√7 x √19 = 2.64575131106459 x 4.35889894354067 = 11.5325625946708

The geometric mean of 7 and 56 is 19.7989898732
28 + 7 = 3535/2 = 17.5
If there are only k numbers x(1),x(2)....,x(k), the geometric mean is the kth root of the product of these k numbers. Example: find the geometric mean of 4,3,7,8 We want the fourth root of 4 x 3 x 7 x 8 = 672 =(672)^(1/4) = 5.09146 is the geometric mean. The geometric mean is normally defined only for a set of positive numbers.
To calculate the geometric mean multiply the numbers together and take the nth root (where n is the number of numbers). geometric mean of 8 & 7 is: √(8 x 7) = √56 ~= 7.48
To find the ARITHMETIC mean of 4 and 10, you add them up and then divide by n number of values: (4+10)/2 = 7 To find the GEOMETRIC mean, you multiply 4 and 10, and then find the nth root: the square root of 40 is 6.32 (to 3 significant figures).
Geometric Mean of two numbers is the square root of their product, in this case root 77 ie 8.775
7.9373 (rounded)
sq root (6 X 7) = about 6.48.
GM(7, 25) = sqrt(7*25) = 13.23 approx.
