Answer 1

#9

$\\ \tt\bull\rightarrowtail 3\sqrt{112}=3\sqrt{16(7)}=3(4)\sqrt{7}=12\sqrt{7}$

• The coefficient is 12

#10

$\\ \tt\bull\rightarrowtail √175=\sqrt{25\times 7}=5\sqrt{7}$

• Radicand is 7

Answer 2

Answer:

$9)3 \sqrt{112} \\ \\ = 3 \sqrt{4 \times 4 \times 7} \\ \\ = 3 \times 4 \sqrt{7} \\ \\ = 12 \sqrt{7} \\ \\ 10) \sqrt{175} \\ \\ = \sqrt{5 \times 5 \times 7} \\ \\ = 5 \sqrt{7}$
