Question $2(1$ point$)$

Evaluate the integral

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}\frac{dx}{x\sqrt[\phantom{2}]{x^{2}7}}$

Select the correct answer.

$)=(1$

$\frac{1}{\sqrt[\phantom{2}]{2}}ln(\frac{\sqrt[\phantom{2}]{x^{2}7}-\sqrt[\phantom{2}]{2}}{x^2})c$

$\frac{1}{\sqrt[\phantom{2}]{5}}|\sqrt[\phantom{2}]{x^{2}7}-\sqrt[\phantom{2}]{7}|dots$

$\frac{1}{\sqrt[\phantom{2}]{5}}ln|\frac{\sqrt[\phantom{2}]{x^{2}7}-\sqrt[\phantom{2}]{2}}{2}|c$
