find absolute value of each complex number
\n" ); document.write( "2+4i=
\n" ); document.write( "/4+16
\n" ); document.write( "/20= 2/5\r
\n" ); document.write( "\n" ); document.write( "my question is how it became from square root of/20 to 2/5?
\n" ); document.write( "

/4 + 16 <===== This is actually , which YOU should've written as: sqrt(4 + 16)
\n" );
document.write( "/20 <========= This is actually  which shoudld've been written as sqrt(20)
\n" );
document.write( "2/5 <========= This is actually , which YOU should've written as 2sqrt(5)
\n" );
document.write( "You CANNOT use \"/\" in place of the square root symbol! \n" );
document.write( "

\n" );
