log5+logx=2?\r
\n" ); document.write( "\n" ); document.write( "remember: logs can be combined as such: Log(x) + Log(y) -> Log(x*y)
\n" ); document.write( "so: log(5) + log(x) = 2
\n" ); document.write( "becomes: log(5*x)=2 or log(5x)=2\r
\n" ); document.write( "\n" ); document.write( "logs can be changed into exponents, and \"log\" is base 10.\r
\n" ); document.write( "\n" ); document.write( "so: log(5x)=2 becomes: 5x= {10^2} (10^2 = 10 squared)
\n" ); document.write( "5x= {10^2}
\n" ); document.write( "5x=100
\n" ); document.write( "divide both sides by 5
\n" ); document.write( "x=20
\n" ); document.write( "
\n" );
