To find a geometric mean, we multiply all of the terms together and take the nth root of the result (where n is the number of terms we are averaging). With 10 and 6, we find the geometric mean is the square root of 10*6 = 60. Sqrt(60) = 2*sqrt(15).
The geometric mean of two numbers is the square root of their product. In this case, the geometric mean of 2 and 6 is the square root of (2 * 6) which equals the square root of 12. Therefore, the geometric mean of 2 and 6 is √12, which simplifies to approximately 3.46.
