Thanks Bobbundy Got it
hi juanIf a^2 > b^2 then a > b provided you stick to positive numbers.So take each expression and square it. You will be left with terms that still have a square root.Simplify and square again.At this stage you can make a direct comparison to determine which is bigger.If you take a look at post 14 on the threadhttp://www.mathisfunforum.com/viewtopic.php?id=18016you see a similar example.Bob
Which one is greater
