The geometric mean of two numbers is calculated by taking the square root of their product. For 180 and 5, the geometric mean is √(180 × 5) = √900. This simplifies to 30, so the geometric mean of 180 and 5 is 30.

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
If, by geometric number (?) you mean geometric mean, then the answer is 40.
Geometric Mean (2, 40) = sqrt(2*40) = sqrt(80) = sqrt(16*5) = 4*sqrt(5) = 8.944 (approx).
Geometric mean of 5 and 15= √(5x15)=√75=5√3
The geometric mean of two numbers is calculated by taking the square root of their product. For 180 and 5, the geometric mean is √(180 × 5) = √900. This simplifies to 30, so the geometric mean of 180 and 5 is 30.
Geometric mean = sqrt(5*80) = sqrt(400) = 20
