​

Answer 1

a)

$3 \sqrt{5} \times 2 \sqrt{2} \sqrt{3} \\ 6 \sqrt{5 \times 2 \times 3} \\ 6 \sqrt{30}$

b)

$\sqrt{2} \sqrt{10} \sqrt{7} \\ \sqrt{2 \times 10 \times 7} \\ \sqrt{140}$

$\sqrt{ {2}^{2} \times 35 } \\ 2 \sqrt{35}$

c)

$\sqrt{36} \sqrt{100} \\ 6 \times 10 \\ 60$

d)

$\frac{ \sqrt{121} }{ \sqrt{144} } \\ \frac{11}{12} = 0.916$

e)

$\frac{ \sqrt{256} }{ \sqrt{169} } \\ \frac{16}{13} = 1.230769$
