I have a question: I'm trying to evaluate a limit but am having a tough time using the limit laws:

lim ( sqrt(121+h) - 11)/ h
h->0

Answer 1

multiplu top and bottom by the conjugate of the top

Answer 2

\[\frac{\sqrt{121+h}-11}{h}*\frac{\sqrt{121+h}+11}{\sqrt{121+h}+11}\]
\[\frac{121+h-121}{h(\sqrt{121+h}+1}\]

Answer 3

\[\frac{1}{\sqrt{121+h}+11}\]
