(2.3)^x=1000 and (0.23)^y=1000


log(2.3)^x =log1000 and log(0.23)^y=1000


xlog(2.3)=log10^3 and log(0.23)^y =log10^3


xlog(2.3) = 3log10 and ylog(0.23) =3log10


xlog(2.3) = 3×1 and ylog(0.23)=3  [log10=1]


⇒log(2.3)=3/x and log0.23 =3/y


/////////////


3/x -3/y =log2.3  -log(0.23)


3(1/x - 1/y) =log(2.3/0.23)


⇒1/x - 1/y ={log(10)}/3


⇒1/x-1/y =(1)/3


⇒1/x -1/y =1/3
