(2+4i)/2i\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when you divide two complex numbers, you must multiply the numerator and the denominator by the complex congugate of the denominator\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(2 + 4i)/2i
\n" ); document.write( "-2i is the complex conjugate of 2i
\n" ); document.write( "(2 + 4i)/2i * (-2i)/(-2i)
\n" ); document.write( "-2i(2 + 4i)/(2i * -2i)
\n" ); document.write( "(-4i - 8i^2)/(-4i^2)
\n" ); document.write( "(-4i + 8)/4 (note i^2 = -1)
\n" ); document.write( "2 - i
