Which one is greater

hi juan

If 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 thread

http://www.mathisfunforum.com/viewtopic.php?id=18016

you see a similar example.
