Answer 1

b) $\sqrt{1} \ \textless \ \sqrt{3} \ \textless \ \sqrt{4} \ \textless \ \sqrt{9} \ \textless \ \sqrt{10}$

$\sqrt{10} = 3,162277660...$

c) $\sqrt{20} = 4,47213595...$

20|2
10|2
  5|5

2*2*5 = $\sqrt[2]{2^2*5} = \sqrt[2]{2^2} * \sqrt[2]{5} = 2 * \sqrt{5}$

$\sqrt{1} \ \textless \ \sqrt{3} \ \textless \ \sqrt{4} \ \textless \ \sqrt{9} \ \textless \ \sqrt{16} \ \textless \ 2* \sqrt{5}$
