Answer 2

$\sqrt{43681} =\sqrt{11*11*19*19} =11*19=209$

$\sqrt{1,1236} =\sqrt{\frac{11236}{10000} } =\sqrt{\frac{2809}{2500} } =\frac{53}{50}$

$\sqrt{0,98013} =\sqrt{\frac{98013}{100000} } =\frac{\sqrt{980130} }{100\sqrt{10} } =\frac{\sqrt{980130} }{1000}$

$\sqrt{514} =\sqrt{514}$

$\sqrt{1,1904} =\sqrt{\frac{11904}{10000} } =\sqrt{\frac{744}{625} } =\frac{2\sqrt{186} }{25}$

$\sqrt{3,681} =\sqrt{\frac{3681}{1000} } =\frac{3\sqrt{409} }{10\sqrt{10} } =\frac{3\sqrt{4090} }{100}$
