Question

If X2+y2=10xy,then prove that 2log(x+y)=log× +log Y +2 log 2 +log 3 ?​

Answer 1

Given x² + y² = 10x

=> x² + y² + 2xy = 10x + 2xy

=> ( x + y )² = 12xy

Take log bothside of the equation ,

log ( x + y )² = log ( 12xy )

=> 2log( x + y ) = log 12 + log x + log y

=> 2log(x+y) = log(2²×3)+logx+logy

=> 2log(x+y)=log2²+log3+logx+logy

=>2log(x+y)=2log2+log3+logx+logy
