16. Geometric mean of two numbers is the square root of their product.
Not usually. Given numbers a and b, the mean or average is (a + b)/2 but the geometric mean is sq rt (a X b). If both a and b equal 1, the results are the same.
Ah, the geometric mean between 1 and 4 is like a little secret garden in the world of numbers. To find it, you simply multiply the two numbers together and then take the square root of that product. So, for 1 and 4, the geometric mean would be the square root of 4, which is 2. Just a happy little calculation to brighten your day.
I'm posting a link which explains it pretty good, but here it is. Given a set of n numbers, the Geometric mean is found by multiplying all of the numbers together, then taking the nth root of this product. The nth root can also be written as taking to the 1/n power.Example: Geometric mean of 8 and 2: There are two numbers, so take the square root of the product. sqrt(8*2) = sqrt(16) = 4.
Assuming that you mean the geometric average, the answer is 40.It's simply the square root (the 1/2 power, because there are 2 numbers) of 32 times 50 (1600).
