If, by geometric number (?) you mean geometric mean, then the answer is 40.
It is 11.6190, approx.
The geometric mean is 45.0
geometric mean of 6 and 30=√(6x30)=√180=6√5
5
45
The geometric mean of 4 and 5 is 4.472135955
Gm = SQRT (9*5) = SQRT (45) = 6.708 (to 3 decimal places)
If, by geometric number (?) you mean geometric mean, then the answer is 40.
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.)
It is 11.6190, approx.
Geometric mean of 5 and 15= √(5x15)=√75=5√3
45
Geometric mean = sqrt(5*80) = sqrt(400) = 20
√24 x √45 = 4.89897948556636 x 6.70820393249937 = 32.86335345031
The geometric mean is 45.0
GM of two numbers is the square root of their product, in this case sqrt 2025 ie 45.
