\n" ); document.write( "\n" ); document.write( "ANSWER:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We have the value i^2 = -1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So,\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(1-9i)-(5-i^2-8i) = 1 - 9i - 5 + i^2 + 8i
\n" ); document.write( "
\n" ); document.write( " = 1 - 9i - 5 + -1 + 8i\r
\n" ); document.write( "\n" ); document.write( " = 1 - 5 + -1 -9i + 8i\r
\n" ); document.write( "\n" ); document.write( " = -5 -1i\r
\n" ); document.write( "
