Question

If ${\log }_5{\log }_5{\log }_2,x=0$, then the value of $x$ is

• A. $32$
• B. $125$
• C. $625$
• D. $25$

Answer 1

Answer: (A)

Given, ${\log }_5{\log }_5{\log }_2,x=0$,

$\Rightarrow {\log }_5{\log }_{2}x=50$

$\Rightarrow {\log }_5{\log }_{2}x=1$

$\Rightarrow {\log }_{2}x=5$

$\Rightarrow x=2^5=32$
