64.99 rounded to the nearest tenth

The above answer is absolute rubbish.
The geometric mean is sqrt(125*5) = sqrt(625) = 25
As it happens, the arithmetic mean is (125 + 5)/2 = 130/2 which is exactly 65. That is nearly the same as the answer given although I cannot understand why it required rounding. Furthermore, 64.99 is a number rounded to the nearest hundredth, not the nearest tenth!
The geometric mean of 4 and 5 is 4.472135955
Geometric mean of 5 and 15= √(5x15)=√75=5√3
Geometric mean = sqrt(5*80) = sqrt(400) = 20
it is 10
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
25
The geometric mean is a positive number x such that x/5 = 25/x. Thus, x2 = 125, so x = 5*sqrt(5).
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
It is 0.2
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
geometric mean of 6 and 30=√(6x30)=√180=6√5
