The answer of u r question is..✌️✌️

Ans:✍️✍️✍️✍️✍️✍️


Let,

( {x + y}^{2} ) =  {x}^{2}  +  {y}^{2}  + 2xy


( {x + y}^{2} ) = 25xy + 2xy


( {x + y)}^{2}  = 27xy


Now apply the log on both side...


 log( {x + y}^{2} )  =  log(27xy)

2 log(x + y)  =  log27 + logx + log \: y

2log(x + y) =  {log}^{ {3}^{3} }  + logx +  log(y)

2log(x + y) = 3  {log}^{3}  + logx + logy

Hence proved...
