There is none, because you cannot have a negative number as part of it.
The geometric mean of 4 and 5 is 4.472135955
If, by geometric number (?) you mean geometric mean, then the answer is 40.
Geometric mean of 5 and 15= √(5x15)=√75=5√3
Geometric mean = sqrt(5*80) = sqrt(400) = 20
The geometric mean is 45.0
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
geometric mean of 6 and 30=√(6x30)=√180=6√5
Two numbers can have only one geometric mean. The geometric mean of 5 and 135 is +sqrt(5*135) = +sqrt(675) = 15*sqrt(3) = 25.98
geometric mean is: (5 x 135)1/2 = √675 ≈ 25.98 To find the geometric mean of n numbers, multiply them together and take the nth root, so the geometric mean of x1, x2, ..., xn is: geometric mean = (Π xr)1/n for r = 1, 2, .., n
