Question

Find the Geometric Mean of 8 and 50. Be sure to show your work!

Answer 1

The answer is: 20

My work: √8*50 = √400 = 20

You have to take the square root of 8 multiplied by 50. With that, you would get 400, which is still squared because you have to get the numbers inside of the square root to one number. After that, you can now take the square root of the number that is inside of it, which in this case it is 400. The square root of 400 is 20.

I hope this helps!

Answer 2

20

Explanation:

The geometric mean of n numbers is the n-th root of their product. For two numbers, it is the square root of their product:

geometric mean = √(8·50) = √400 = 20
