Answer 1

Ответ:

а)

$\sqrt{0.25} - 196 = \sqrt{ \frac{1}{4} } \times 196 = \frac{1}{2} \ \div 196 = 98$

b)

$\sqrt{6} \sqrt{24} = \sqrt{6 \times 24} = \sqrt{144} = 12$

c)я не знаю

d)

$\sqrt{17} \div \sqrt{3.5} = \sqrt{17 \div 3.5} = \sqrt{17 \div \frac{7}{2} } = \sqrt{17 \times \frac{2}{7} }$
