√15 x √20 = 3.87298334620742 x 4.47213595499958 = 17.3205080756888
√18 x √3 = 4.24264068711928 x 1.73205080756888 = 7.34846922834953
Geometric mean of 5 and 15= √(5x15)=√75=5√3
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
√3 x √15 = 1.73205080756888 x 3.87298334620742 = 6.70820393249937
The geometric mean of 3 and 75 is 15.0
The geometric mean of 15 and 24 is 18.973665961
Just use the definition of geometric mean. Multiply all the numbers together, then take the square root. (In this case, it is the square, or second, root, because there are two numbers; for the geometric mean of three numbers, you take the cubic root, etc.)
15 is the geometric mean of 25 and 35.
The geometric mean of 3 and 27 is 9.0
The geometric mean of 16 and 3 is 6.92820323028
sqrt(8*15) is the geometric mean. sqrt(120)=2*sqrt(30)
