Ответ:
а) \((21.2544 : 0.9 + 1.02 \cdot 3.2) : 5.6\)
\(21.2544 : 0.9 = 23.616\)
\(1.02 \cdot 3.2 = 3.264\)
\((23.616 + 3.264) : 5.6 = 26.88 : 5.6 = 4.8\)
б) \(4.36 : (3.15 + 2.3) + (0.792 - 0.78) \cdot 350\)
\(3.15 + 2.3 = 5.45\)
\(4.36 : 5.45 = 0.8\)
\(0.792 - 0.78 = 0.012\)
\(0.012 \cdot 350 = 4.2\)
\(0.8 + 4.2 = 5\)
Ответ: а) 4,8; б) 5.
