Solution

The correct option is B $10$
$2 log x - log y = 1$
Assuming base 10
$2 log x - log y = log 10 2 log x = log 10 + log y log x^{2} = log 10 y$
Removing log, $x^{2} = 10 y$

log (\frac{x + y}{3}) = \frac{1}{2} (log x + log y)

then find the valued

x^{2} + y^{2} - 25 x y, t h e n p r o v e 2 l o g (x + y) = 3 l o g 3 + l o g x + l o g y

log (\frac{x + y}{5}) = \frac{1}{2} (log x + log y)

\frac{x}{y} + \frac{y}{x} =

x^{2} + y^{2} = 25 x y

2 l o g (x + y) = 3 l o g 3 + l o g x + l o g y

x^{2} + y^{2} = 25 x y,

then prove that

2 log (x + y) = 3 log 3 + log x + log y .
