Find the geometric mean of the numbers 6, 72, and 108.
Find the geometric mean of the numbers six, 72, and 108.
To find the geometric mean, we multiply the three numbers together and then take the cube root. Six times 72 times 108 equals 46656. From there, we can use our calculator to find the cube root of 46656. This will tell us what number multiplied by itself three times gives us 46656. Once we do that, it returns the number 36. The geometric mean of these three numbers is 36.
