To find the geometric mean of any two numbers,
take the square root of their product.
sqrt( 3 x 48 ) = sqrt( 144 ) = 12
3/12 = 12/48 = 0.25

No, it is 12.
No. It is 12Here is why:The geometric mean of 3 and 48 is the square root of 3x38=144So it is the square root of 144 which is 12.In general, the geometric mean of the numbers a1 a2 ....an is the nth root of the product of the ai from i=1 to i=n
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
To find the ARITHMETIC mean of 4 and 10, you add them up and then divide by n number of values: (4+10)/2 = 7 To find the GEOMETRIC mean, you multiply 4 and 10, and then find the nth root: the square root of 40 is 6.32 (to 3 significant figures).
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
