Simplifying Radical Expressions
Posted:
Nov 26, 2004 1:11 AM


Hi, I have a quick little problem that I should be able to understand, but for some reason the solution is eluding me.
SQRT(3 + 2 * SQRT(2))  SQRT(3  2 * SQRT(2))
I know that this expression simplifies to 2, but I cannot figure out why. Any suggestions on how to approach this type of problem would be most appreciated.
Thanks!
