MCQ
The solution of ${\log _{\sqrt 3 }}x + {\log _{\sqrt[4]{3}}}x + {\log _{\sqrt[6]{3}}}x + ......... + {\log _{\sqrt[{16}]{3}}}x = 36$ is
- A$x = 3$
- B$x = 4\sqrt 3 $
- C$x = 9$
- ✓$x = \sqrt 3 $
$ \Rightarrow $$\frac{1}{{{{\log }_x}\sqrt 3 \,}} + \frac{1}{{{{\log }_x}\sqrt[4]{3}}} + \frac{1}{{{{\log }_x}\sqrt[6]{3}}} + ... + \frac{1}{{{{\log }_x}\sqrt[{16}]{3}}} = 36$
$ \Rightarrow $ $\frac{1}{{(1/2){{\log }_x}3}} + \frac{1}{{(1/4){{\log }_x}3}} + \frac{1}{{(1/6){{\log }_x}3}} + ..... + \frac{1}{{(1/16){{\log }_x}3}} = 36$
$ \Rightarrow $ $({\log _3}x)(2 + 4 + 6 + ..... + 16) = 36$
$ \Rightarrow $ $({\log _3}x)\frac{8}{2}[2 + 16] = 36$
$ \Rightarrow $${\log _3}x = \frac{1}{2}$
$ \Rightarrow $$x = {3^{1/2}}$
$ \Rightarrow x = \sqrt 3 $.
