Answer 1

Geometric mean is the nth root of the product of n numbers

For two numbers it's the square root

for three numbers it's the cube root

for 4 numbers it's the fourth root

etc.

--------------------------

5 and 20

m = √(5 * 20) =

m = √100

m = 10

3 and 12

m = √(3 * 12)

m = √36

m = 6

do the rest the same way
