You can put this solution on YOUR website!
3^(log(9,4))=2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%5E%28log%289%2C4%29%29=2\" ?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Look into that \"log%289%2C4%29\". Change of Base formula might be helpful....\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"log%2810%2C4%29%2Flog%2810%2C9%29=log%289%2C4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Look in table of logs or use calculator:
\n" ); document.write( "\"log%289%2C4%29=%280.60206%29%2F%280.9542425%29=0.63093\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%5E0.63093\", and you might use logs table again...\r
\n" ); document.write( "\n" ); document.write( "Result is something extremely close to 2.
\n" ); document.write( "
\n" );
