This will get rid of the radical in the denominator.\r \n" ); document.write( "\n" ); document.write( "(7(3+5i))/((3-5i)(3+5i)) = \n" ); document.write( "(7(3+5i))/(9-25(i^2)) but i^2 is -1, so\r \n" ); document.write( "\n" ); document.write( "(7(3+5i))/(9+25)= \n" ); document.write( "7(3+5i)/34\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " \n" ); document.write( " |
