Could someone help me with this problem?

lim ((3√x) -1)
x->1 ((√x) - 1)

What I did was multiply both sides by ((√x) + 1) as the conjugate.



lim ((3√x) -1) x ((√x) + 1)
x->1 ((√x) - 1) x ((√x) + 1)

which I got...

lim 3x-1
x->1 x-1

I'm not sure what to do next, if anyone could give a tip, that be great.

[input]plot( ( 3*sqrt(x)-1 ) / ( sqrt(x) -1 ), x=0..2, -100..100)[/input]

two sided limit:
none

one sided limits:
lim x->1+ = inf
lim x->1- = -inf

hello out there, maybe you have heard it said,that great minds can't do simple math. e.g. einstein. now to save myself the embarrassment of asking such a simple question, let me just say first; my knowledge of math is so vast that there are many gaps.
