Question

Find the geometric mean of the numbers 9,21, and 49

Answer 1

Geometric mean of a list of numbers is (product of elements)^{1/(numbers of elements)}

Geometric mean of three numbers is cube root of their product.

Given numbers are 9, 21 and 49.

Geometric mean = ∛ (9 * 21 * 49)

= (9261)^1/3

=21.

Geometric mean of 9, 21 and 49 is 21.

 

Answer 2

Geometric mean of two numbers is squre root of thir product.

Given numbers are 9,21,49

Geometric mean = √9*21*49

= √9261

=96.23

Comments

Geometric mean of 9,21,49 is 21.
