Express (I) i^(-4k) and (ii) i^(-(4k+1)), where i is the imaginary number and k is a positive constant,in the simplest form or in term of i.
\n" ); document.write( "-------
\n" ); document.write( "i^(-4k) = 1/i^(4k) = 1/1 = 1
\n" ); document.write( "================================
\n" ); document.write( "i^(-(4k+1))
\n" ); document.write( "= 1/i^(4k+1)
\n" ); document.write( "= 1/(i^(4k)*i)
\n" ); document.write( "= 1/(1*i)
\n" ); document.write( "= 1/i
\n" ); document.write( "= i/i^2
\n" ); document.write( "= i/-1
\n" ); document.write( "= -i\r
