Question

What is the geometric mean of 3 and 147?

Answer 1

3×147= 441
Then (as there are two numbers) take the square root:

`√(441)`

`√(21)`
I think it is 21 square root

.

Answer 2

to find the geometric mean, multiply them together, then take the square root

3*147

441

sqrt(441)

21

The geometric mean is 21
