Geometric Mean of 'n' numbers is defined as the '1/n'th power of the product of the 'n' terms. You have 2 terms here. Try to work out accordingly.
I am asked to find the geometric means of 8 and 20
I set up this formula:
8 x
_ __
X 20
edit: the formatting came out inaccurate, but the formula that I set up was 8 over X and X over 20.
But my answer came out to be a decimal answer. The back of my textbook has the answer 4 squareroot 10
Please help me! Also, please elaborate the steps with how to get that answer. Thank You!
