Easy one, just want a confirmation...limit problem

[hank]

find the limit as x-> infinity of x^(1/2) lnx. //square root of x times lnx

I'm pretty sure it's just infinity.

It's not an indeterminate form, is it?

Thanks,

(Going over some of my test questions from today's test, and I bombed it. Grrrrr)

Most definitely NOT an indeterminate form.

Both pieces increase without bound. Multiplied together, this expression just keeps going.

Thanks, that's what I figured.

Don't know why I thought that when I did the test.
