2. Вычисление корней:
- \( \sqrt{0,81} = 0,9 \)
- \( \sqrt[3]{-216} = -6 \)
- \( \sqrt[4]{625} = 5 \)
- \( \sqrt{\frac{144}{25}} = \frac{12}{5} \)
- \( \sqrt{1,21} = 1,1 \)
- \( \sqrt[3]{1000} = 10 \)
- \( \sqrt{\frac{36}{49}} = \frac{6}{7} \)
- \( \sqrt[5]{-32} = -2 \)
- \( \sqrt{0,04} = 0,2 \)
- \( \sqrt[3]{-0,001} = -0,1 \)
- \( \sqrt{\frac{1}{16}} = \frac{1}{4} \)
- \( \sqrt[4]{\frac{81}{16}} = \frac{3}{2} \)
Ответ: 0,9; -6; 5; 12/5; 1,1; 10; 6/7; -2; 0,2; -0,1; 1/4; 3/2.
