यदि $x = {\log _3}5,\,\,\,y = {\log _{17}}25$ हो, तो निम्न में से कौन सा सही है

A

$x < y$

B

$x = y$

C

$x > y$

D

इनमें से कोई नहीं

(IIT-1993)

Solution

$y = {\log _{17}}25 = 2{\log _{17}}5$

$\frac{1}{y} = \frac{1}{2}{\log _5}17$

$\frac{1}{x} = {\log _5}3 = \frac{1}{2}{\log _5}9$

स्पष्टत: $\frac{1}{y} > \frac{1}{x}$ , $x > y$
