geometric means is when you take a square root of the product of 2 or more numbers
sqrt (8 * 18)
sqrt (2 * 2 * 2 * 2 * 3 * 3)
2 * 2 * 3
12

To find the geometric mean, you multiply the numbers together and take the nth root of the solution, where n is the number of numbers....so, if your numbers are 8 and 32, you would multiply 8 X 32 = 256 and take the 2nd root of 256 (which is the square root) so the answer is 16. If you had 3 numbers, say 2, 8, and 32, you would multiply 2 X 8 X 32 = 512 and take the cube (3rd) root of 512, which is 8.

GM = sqrt(ab)
GM = sqrt(8*18) = sqrt144 = 12
