Please help me solve this equation:
\n" ); document.write( "1.- $\"log%288%2C+%281024%29%29=x%2B3+\"$
\n" ); document.write( "8^(x+3)=1024
\n" ); document.write( "(x+3)log(8)=log(1024)
\n" ); document.write( "x+3=log(1024)/log(8)
\n" ); document.write( "x=log(1024)/log(8)-3=0.3333…
\n" ); document.write( "...
\n" ); document.write( "2.- $\"log%28x%2C+%288%29%29=3\"$
\n" ); document.write( "x^3=8=2^3
\n" ); document.write( "x=2
\n" ); document.write( "..
\n" ); document.write( "3.- $\"log%285%2C%28.15+%2A+10%5E2%29%29=x\"$
\n" ); document.write( " $\"log%285%2C%2815%29%29=x\"$
\n" ); document.write( "5^x=15
\n" ); document.write( "x log5=log15
\n" ); document.write( "x=log15/log5=1.68 \n" ); document.write( "

\n" );
