Question

UpStudy AI · Accepted Answer

Calculate or simplify the expression $$ \lim_{x\rightarrow 2} \sqrt{\frac{x^{2}+5}{x-1}} $$.
Evaluate the limit by following steps:
- step0: Evaluate the limit:
  $$\lim _{x\rightarrow 2}\left(\sqrt{\frac{x^{2}+5}{x-1}}\right)$$
- step1: Rewrite the expression:
  $$\sqrt{\lim _{x\rightarrow 2}\left(\frac{x^{2}+5}{x-1}\right)}$$
- step2: Calculate:
  $$\sqrt{9}$$
- step3: Write in exponential form:
  $$\sqrt{3^{2}}$$
- step4: Simplify the root:
  $$3$$
