mm but how? maybe something like this? \[\frac{ x ^{2} +\sqrt{x} }{ x ^{2} +\sqrt{x} }\] multiply the original function times the rationalization of the numerator?

yeep, i know the limit, but what i dont, is how to find it

mm but how can i find the limit without using L'hopital? cos my teacher doesnt allow me to do that yet, he want me to find the limit algebraically

zordoloom Group TitleBest ResponseYou've already chosen the best response.1
Just multiply top and bottom by conjugates then.

appleduardo Group TitleBest ResponseYou've already chosen the best response.0
respectively? i mean the numerator conjugate times the original numerator and the denominator conjugate times the original denominator?

What you want to do is rationalize one side.
 2 years ago

zordoloom Group TitleBest ResponseYou've already chosen the best response.1
So, just multiply top and bottom by 1+sqrt(x)
 2 years ago

zordoloom Group TitleBest ResponseYou've already chosen the best response.1
You should get 1x for the bottom
