Give the principal roots of each of the following. ( for square roots, assume the principal square is required unless the problem indicates otherwise.)
\n" ); document.write( "5. √49= 7
\n" ); document.write( "----
\n" ); document.write( "If that 3 indicates cube root the answer is
\n" ); document.write( "6. 3√-27= -3
\n" ); document.write( "If the problem is 3*sqrt(-27) the answer is 3*3*sqrt(3)i
\n" ); document.write( "= 9sqrt(3)i\r
\n" ); document.write( "\n" ); document.write( "====================
