Answer 1

Break the argument of the square root into a prime factorization, then pull out all the perfect squares from inside.\[-11\sqrt {112}=-11\sqrt{2^4*7}=-44\sqrt{7}\]

Answer 2

multiply by \[\sqrt{112}/\sqrt{112}\]

gives

\[-11 \times \sqrt{112}/112\\[= -11 \times4\sqrt{7}/112\]]

\[= -11\sqrt{7}/28\]
