Вычислите 1)√4/25; 2)√9/121; 3)√81/225 4)√100/289 5)√5^2; 6)√0,8^2; 7)√16^2; 8)√3,24^2 Помогите пожалуйста

$\sqrt{\frac{4}{25}} = \frac{\sqrt{4}}{\sqrt{25}} = \frac{2}{5} = 0,4$

$\sqrt{\frac{9}{121}} = \frac{\sqrt{9}}{\sqrt{121}} = \frac{3}{11} \approx 0,2727$

$\sqrt{\frac{81}{225}} = \frac{\sqrt{81}}{\sqrt{225}} = \frac{9}{15} = 0,6$

$\sqrt{\frac{100}{289}} = \frac{\sqrt{100}}{\sqrt{289}} = \frac{10}{17} \approx 0,588$

$\sqrt{5^2} = \sqrt{25} = 5$

$\sqrt{0,8^2} = \sqrt{0,64} = 0,8$

$\sqrt{16^2} = \sqrt{256} = 16$

$\sqrt{3,24^2} = \sqrt{10,4976} \approx 3,24$
