3) -3\(\frac{1}{3}\)\(\cdot\)\(\left\)\(-1\frac{2}{7}\right\)\(\cdot\)(-3)\(\cdot\)(-7)
Ответ:
Решение:
\(-3\frac{1}{3}\cdot\left(-1\frac{2}{7}\right)\cdot(-3)\cdot(-7) = \left(-\frac{10}{3}\right) \cdot \left(-\frac{9}{7}\right) \cdot 21 = \frac{10\cdot 9\cdot 21}{3\cdot 7} = 10\cdot 3\cdot 21 = 630\)
Ответ: 630
