How Do You Rationalize the Numerator with Square Roots in Limits?

[afcwestwarrior]

when u use square roots, here's an example
lim 9-t/3-squareroot of t
t approaches 9
all i need is an example on how u rationalize the sqaure root of something, i know how to rationalize regular stuff, but i forgot how to rationalize sqaure roots

I hope I've understood your question: you wish to rationalise a surd (which is irrational)? No it can't be done.

Would you like to rewrite the question in Latex? I'm not quite sure what it is that you're trying to do. Perhaps you are taking the wrong approach?
