Question 945136

{{{2log(4*5)-2log(8*5)+log(80*81)-3log(2)=-1}}}

{{{2log((4))+2log((5))-log((2^3*5))+log(2^4*5*3^4)-3log(2)=-1}}}

{{{2log(2^2)+2log(5)-log(2^3)+log(5)+log(2^4)+log(5)+log(3^4)-3log(2)=-1}}}

{{{4log(2)+2log(5)-3log(2)+log(5)+4log(2)+log(5)+4log(3)-3log(2)=-1}}}

{{{4log(2)+4log(2)-3log(2)-3log(2)+2log(5)+log(5)+log(5)+4log(3)=-1}}}

{{{2log(2)+4log(5)+4log(3)=-1}}}

{{{log(2^2)+log(5^4)+log(3^4)=-1}}}

{{{log(2^2*5^4*3^4)=-1}}}


{{{5.3107398866=-1}}} which is false

so, {{{highlight(2log(4*5)-2log(8*5)+log(80*81)-3log(2)<>-1)}}}
