Answer 1

$heya \\ \\ \\ some \: formula \: of \: log \\ \\ \\ log(x {}^{n} ) = n log( x) \\ \\ \\ \\ and \: \: \: \: \\ \\ \\ log(m \times n) = log(m) + log(n) \\ \\ \\ \\ \\ \\ (x + y) {}^{2} - 2xy = 25xy \\ \\ \\ \\ taking \: log \: on \: both \: sides \\ \\ \\ \\ log(x + y) {}^{2} = log(3 {}^{3} \times x \times y) \\ \\ \\ 2 log(x + y) = 3 log(x) + log(x) + log(y)$
