Question

Find mean proportional of 9 and 16 step by step.

Answer 1

Explanation:

To find the mean proportional, that is the geometric mean, we first multiply the two numbers and then, find the product's square root.

Given two numbers are 9 and 16.

9 x 16 = 144 = 2 x 2 x 2 x 2 x 3 x 3

Hence, the square root of 144 is 2 x 2 x 3 = 12.

Hence, the mean proportional of 9 and 16 is 12.

Answer: 12
