Answer :

The geometric mean of the numbers 169 and 9 is found by multiplying them together to get 1521 and then taking the square root of that product, resulting in a geometric mean of 39.

To find the geometric mean of the pair of numbers 169 and 9, you use the formula for the geometric mean which involves taking the product of the two numbers and then finding the square root of that product. The calculation is as follows:

Geometric Mean = √(169 × 9)

First, multiply the numbers:

169 × 9 = 1521

Next, take the square root of the result:

√1521 = 39

Therefore, the geometric mean of 169 and 9 is 39.
