differentiation

Question: If $y = {\log _{10}}x + {\log _x}10 + {\log _x}x + {\log _{10}}10,$then $\frac{{dy}}{{dx}} = $

1) $\frac{1}{{x{{\log }_e}10}} - \frac{{{{\log }_e}10}}{{x{{({{\log }_e}x)}^2}}}$

2) $\frac{1}{{x{{\log }_e}10}} - \frac{1}{{x{{\log }_{10}}e}}$

3) $\frac{1}{{x{{\log }_e}10}} - \frac{{{{\log }_e}10}}{{x{{({{\log }_e}x)}^2}}}$

4) None of these
