Answer 1

im going to write the problem

Answer 2

\[-3\sqrt{120} \]

Answer 3

how did you do that

Answer 4

its ok thanks

Answer 5

\[-3 \sqrt{120}=-3\sqrt{4*30}\]There is a rule for square roots of products which states:\[\sqrt{ab} = \sqrt a \sqrt b\]We apply this rule to get:\[-3 \sqrt{4} \sqrt{30}=-3(2) \sqrt {30} = -6 \sqrt{30}\]
