Solve the logarithmic equation:
\n" ); document.write( "Log(base 2(x+3)+log(base 2(x-3))=4
\n" ); document.write( " $\"log%282%2C%28x%2B3%29%29%2Blog%282%2C%28x-3%29%29=4\"$
\n" ); document.write( " $\"log%282%2C%28%28x%2B3%29%28x-3%29%29%29=4\"$
\n" ); document.write( " $\"log%282%2C%28x%5E2-9%29%29=4\"$
\n" ); document.write( "2^4=x^2-9
\n" ); document.write( "16=x^2-9
\n" ); document.write( "x^2=25
\n" ); document.write( "x=-5 (reject)
\n" ); document.write( "or
\n" ); document.write( "x=5 \n" ); document.write( "

\n" );
