Find the geometric mean for 7 & 12 please.?

Question

I thought it would just be a mean, like an average but apparently it is not 9.5. Does anyone even know what a geometric mean is?

Thank you in advance.

Thank you mrfahrenbacher. :)

Answer 1

Geometric Mean is pretty cool.

Arithmetic Mean: Add up n items and divide by n.
Geometric Mean: Multiply n items and take nth root.

So SquareRoot(7*12) = 9.165

If there were 3 items, you'd take the cubed root.

Answer 2

Geometric propose a sort of well-known. to discover the geometric propose of a sequence of n numbers, multiply the numbers and then take the nth root of the product. formulation: Geometric propose= n sq. root of (a1xa2xa3xa4xa5.....an) Ex.for the quantity 4 and 9 geometric propose=sq. root of 4x9=6 word that we took the sq. root simply by fact we had 2 numbers! answer on your issue geometric propose of seven and 12 =sq. root of 7x12=9.a hundred sixty five
