Step-by-step Solution
Давайте посчитаем оба выражения.
а) \( 50 \cdot 1,34 \cdot 0,2 \):
\[
50 \cdot 1,34 = 67
\]
\[
67 \cdot 0,2 = 13,4
\]
Таким образом, \( 50 \cdot 1,34 \cdot 0,2 = 13,4 \).
б) \( -75,7 \cdot 0,5 \cdot 20 \):
\[
-75,7 \cdot 0,5 = -37,85
\]
\[
-37,85 \cdot 20 = -757
\]
Таким образом, \( -75,7 \cdot 0,5 \cdot 20 = -757 \).
Итак, результаты:
а) \( 13,4 \);
б) \( -757 \).
Quick Answer
а) \( 13,4 \);
б) \( -757 \).
