Not sure how to type it, but the question is write the following radical in simplest form:
\n" ); document.write( " If you can express is at a real number: (a small 4 outside the radical sign), radical sign -16.
\n" ); document.write( ":
\n" ); document.write( " $\"4sqrt%28-16%29\"$ , the 4th root of -16
\n" ); document.write( "we can factor this like this
\n" ); document.write( " $\"4sqrt%282%2A2%2A2%2A2%2A-1%29\"$
\n" ); document.write( "extract the square root of -1
\n" ); document.write( " $\"i%2A4sqrt%282%2A2%2A2%2A2%29\"$
\n" ); document.write( "obviously the 4th root is 2, so we have just
\n" ); document.write( "2i\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
