i^-7
\n" ); document.write( "we can make it a positive exponent by moving it to the denominator:
\n" ); document.write( "1/i^7
\n" ); document.write( "1/(i*i*i*i*i*i*i)
\n" ); document.write( "1/(-1*i*i*i*i*i)
\n" ); document.write( "1/(-1*-1*i*i*i)
\n" ); document.write( "1/(i*i*i)
\n" ); document.write( "1/(-1*i)
\n" ); document.write( "1/(-i)
\n" ); document.write( "or
\n" ); document.write( "-1/i
\n" ); document.write( " \n" ); document.write( "
