Решение 4. №11.32 (с. 65)
Решение 5. №11.32 (с. 65)
Решение 6. №11.32 (с. 65)
а) $5 - \frac{1}{7} \cdot \sqrt{1\frac{27}{169}}$
1. Преобразуем смешанное число под корнем в неправильную дробь: $1\frac{27}{169} = \frac{1 \cdot 169 + 27}{169} = \frac{196}{169}$.
2. Извлечем квадратный корень: $\sqrt{\frac{196}{169}} = \frac{\sqrt{196}}{\sqrt{169}} = \frac{14}{13}$.
3. Выполним умножение: $\frac{1}{7} \cdot \frac{14}{13} = \frac{1 \cdot 14}{7 \cdot 13} = \frac{2}{13}$.
4. Выполним вычитание: $5 - \frac{2}{13} = 4\frac{13}{13} - \frac{2}{13} = 4\frac{11}{13}$.
Ответ: $4\frac{11}{13}$.
б) $8 \cdot \sqrt{5\frac{1}{16}} + 3$
1. Преобразуем смешанное число под корнем в неправильную дробь: $5\frac{1}{16} = \frac{5 \cdot 16 + 1}{16} = \frac{81}{16}$.
2. Извлечем квадратный корень: $\sqrt{\frac{81}{16}} = \frac{\sqrt{81}}{\sqrt{16}} = \frac{9}{4}$.
3. Выполним умножение: $8 \cdot \frac{9}{4} = \frac{8 \cdot 9}{4} = 2 \cdot 9 = 18$.
4. Выполним сложение: $18 + 3 = 21$.
Ответ: $21$.
в) $2 \cdot \sqrt{1\frac{9}{16} - 1}$
1. Выполним вычитание под корнем: $1\frac{9}{16} - 1 = \frac{9}{16}$.
2. Извлечем квадратный корень: $\sqrt{\frac{9}{16}} = \frac{\sqrt{9}}{\sqrt{16}} = \frac{3}{4}$.
3. Выполним умножение: $2 \cdot \frac{3}{4} = \frac{6}{4} = \frac{3}{2} = 1,5$.
Ответ: $1,5$.
г) $4 - \frac{1}{4} \cdot \sqrt{5\frac{11}{49}}$
1. Преобразуем смешанное число под корнем в неправильную дробь: $5\frac{11}{49} = \frac{5 \cdot 49 + 11}{49} = \frac{245+11}{49} = \frac{256}{49}$.
2. Извлечем квадратный корень: $\sqrt{\frac{256}{49}} = \frac{\sqrt{256}}{\sqrt{49}} = \frac{16}{7}$.
3. Выполним умножение: $\frac{1}{4} \cdot \frac{16}{7} = \frac{1 \cdot 16}{4 \cdot 7} = \frac{4}{7}$.
4. Выполним вычитание: $4 - \frac{4}{7} = 3\frac{7}{7} - \frac{4}{7} = 3\frac{3}{7}$.
Ответ: $3\frac{3}{7}$.
