To find the geometric mean of any two numbers,take the square root of their product.sqrt( 3 x 48 ) = sqrt( 144 ) = 123/12 = 12/48 = 0.25
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
GM of two numbers is the square root of their product, which in this case is 48, Sqrt 48 is (almost 7) sqrt 16 x sqrt 3 = 4 x sqrt 3 = 4 x 1.732 = 6.93 to the nearest hundredth.
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
