[tex]

\lim_{x\to 4}\left(\frac{2-\sqrt{x}}{3-\sqrt{2x+1}}\right) [/tex]

[tex]

\lim_{x\to 0}\left(\frac{2^2^x {-2^x}}{2^x{-1}}\right) [/tex]

3. The attempt at a solution

I tried rationalizing but doesn't really help in evaluating these limits.

If a limit cannot be factored, what other ways are there of evaluating limits?
