how to solve:
\n" ); document.write( "log₂(x²)=(log₂x)²
\n" ); document.write( "2log2(x)=[log2(x)]^2
\n" ); document.write( "[log2(x)]^2-2log2(x)=0
\n" ); document.write( "log2(x)(log2(x)-2)=0
\n" ); document.write( "log2(x)=0 (reject, log2(x)>0)
\n" ); document.write( "log2(x)-2=0
\n" ); document.write( "log2(x)=2
\n" ); document.write( "x=4
\n" ); document.write( " \n" ); document.write( "
\n" );
