Express $\"%287i%5E5-2i%5E6%29%2F%283i%5E10%2Bi%5E7%29\"$ in the form a+bi
\n" ); document.write( "--------------
\n" ); document.write( "Eliminate the exponents
\n" ); document.write( " $\"i%5E2+=+-1\"$
\n" ); document.write( " $\"i%5E3+=+-i\"$
\n" ); document.write( " $\"i%5E4+=+%2B1\"$
\n" ); document.write( "---------------
\n" ); document.write( " $\"%287i%2B2i%29%2F%28-3i-i%29\"$
\n" ); document.write( "= 9i/-4i = -9/4
\n" ); document.write( "----------------
\n" ); document.write( "or, (-9/4) + 0i
\n" ); document.write( " \n" ); document.write( "

\n" );
