i^1=i
\n" ); document.write( "i^2=-1
\n" ); document.write( "i^3=-i
\n" ); document.write( "i^4=1
\n" ); document.write( "and they repeat.
\n" ); document.write( "So i^71 is 71/4 is 17 with remainder 3, so it is i^3=-i
\n" ); document.write( "i^121 is 121/4 or 30 with remainder 1, so it is i.
\n" ); document.write( "
\n" );
