lim sqrt(x)/sqrt(10x+1) ?? Limit as x tends to infinity of sqrt(x)/sqrt(10x+1) = sqrt(1/10), but how? I'm trying to understand this, so, it's the sqrt[x/(10x+1)], but how do i simplify that to make it a limit i can set to infinity. I know the problem isn't my calculus skills, but my algebra skills!
