limit x mendekati 5 X min 5 per akar x + 4 min 3.minta bantuannya kak..

[tex]limit \: 5 \: = \frac{x - 5}{ \sqrt{x + 4 - 3 } } \\ = \frac{x - 5}{ \sqrt{x+1} } \times \frac{ \sqrt{ x+1 } }{ \sqrt{x+1} } \\ = \frac{ \sqrt{x+1} 5 - 5}{{x+1} } \\ = \frac{ \sqrt{x+1} }{x+1} \\ = \frac{ \sqrt{6} }{6} \\ = \frac{ \sqrt{6} }{ \sqrt{36} } \\ = \frac{ \sqrt{1} }{ \sqrt{6} } \\ = \frac{1}{ \sqrt{6} } \\ = \frac{1}{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } \\ = \frac{1}{6} \sqrt{6} [/tex]
Semoga bermanfaat
