Question 101784: Please help me. I am having problem understanding this question.

: If your test score are 80 and 100, then the arithmetic mean of your scores is 90. The geometric mean of the scores is a number x such that
80/x = x/100
Are you better off with the arithmetic mean or the geometric mean?
Thank you for your help.

---------------
Find the geometric mean:
80/x = x/100
x^2 = 80*100
x = 89.443
