how do you solve
\n" ); document.write( "log7 x+2 log7 x - log7 3=log7 72
\n" ); document.write( "log7(x)+log7(x^2)-log7(3)=log7(72)
\n" ); document.write( "log7(x)+log7(x^2)-log7(3)-log7(72)=0
\n" ); document.write( "place under single log
\n" ); document.write( "log[x(x^2)/(3*72)]=0
\n" ); document.write( "convert to exponential form
\n" ); document.write( "10^0=x^3/216=1
\n" ); document.write( "x^3=216
\n" ); document.write( "x=6 \n" ); document.write( "

\n" );
