The geometric mean is the square root of the product of the two numbers.
sqrt(35)

The geometric mean between 5 and 7 is given by x^2=7*5
Thus x^2=35
x= sqrt(35)
Another way of describing the geometric mean x between 5 an 7 is:
5/x = x/7

To get the geometric mean, you must multiply the 5 and the 7 together.
5x7=35
Then, you simply take the square root of the answer you get.
sqrt(35)=5.91607978

The geometric mean is the nth root of the product of n numbers. In the case of two numbers, it is the square root.
The square root of 35 is approximately 5.91608
The geometric origin of the geometric mean is explained nicely here:

JimBurnell got it right.
In general, the geometric mean of a list of 'n' numbers is the 'n'th root of the product of all 'n' numbers.
For example, for 5, 7, 9, 11
we would find the fourth root of 5*7*9*11:
Fourth root of 3465 = square root of 58.86425... = 7.6723...
