Answer 1

1

$\sqrt{81} = 9\\\sqrt{\frac{9}{16}} = \frac{3}{4}\\\sqrt{0.04} = 0.2$

2

$\frac{\sqrt{126-54}}{2} = \frac{\sqrt{72}}{2} = \frac{6\sqrt{2}}{2} = 3\sqrt{2}\\\frac{\sqrt{27+22}}{2} = \frac{\sqrt{49}}{2} = \frac{7}{5} = 1.4\\\frac{\sqrt{0.25} + \sqrt{0.01}}{3} = \frac{0.5 + 0.1}{3} = \frac{0.6}{3} = 0.2$

3

$b = \sqrt{2S}$

4

$(4, 5)\\(9, 10)\\(12, 13)$

5

$\sqrt{62} > \sqrt{26}\\\sqrt{234} < 16\\-\sqrt{5} > -\sqrt{6}$
