Logarithm question

Answer 1

\[7\ln \left| \frac{ x+\sqrt{x^{2} - 7} }{ \sqrt{7} } \right| = 7(\ln \left| x+\sqrt{x ^{2}-7} \right| -\ln \sqrt{7} \]

Answer 2

are we asked to prove?

Answer 3

you're missing a bracket

and call that numerator inside the log something like "A" and re-write it again. it might look way less foreboding

Answer 4

\[\log a^x = x \log a~~~~ and ~~~~ \log a - \log b = \log \frac{ a }{ b }\]

Answer 5

hey ln|x|= ln x i mean u can remove it

Answer 6

proof
