It is sqrt(8) = 2.8284, approx.
√29 x √12 = 5.3851648071345 x 3.46410161513775 = 18.6547581061776
21.2132
Geometric mean of 2 and 8 = sqrt(2*8) = sqrt(16) = 4
The geometric mean is 45.0

An arithmetic-geometric mean is a mean of two numbers which is the common limit of a pair of sequences, whose terms are defined by taking the arithmetic and geometric means of the previous pair of terms.
6 (six)
3.4641 (rounded)
It is sqrt(8) = 2.8284, approx.
Multiply the two numbers together and take their square root.
It is sqrt(8) = 2.8284, approx.

Geometric mean of 2 and 8 = sqrt(2*8) = sqrt(16) = 4
The geometric mean of two numbers is the square root of their product. In you instance any two factors of 900 will have a geometric mean of 30 eg 2 & 450 (2 x 15 = 30, 30 x 15 = 450); 3 & 300 (3 x 10 = 30, 30 x 10 = 300); 6 & 150 (6 x 5 = 30, 30 x 5 = 150) etc etc
