Question 157892: If your test scores are 80 and 100, then the arithmetic mean of you scores is 90. The geometric mean of the scores is a number h such that
80/h=h/100
Are you better off with the arithmetic mean or the geometric mean?

You can put this solution on YOUR website!
80%2Fh=h%2F100
You can cross multiply to get,
h%5E2=8000
h=89.44
Keep the 90.
