1. Вычислите:
a) $$ (4^3 + 14^2): 13 $$
1) $$4^3 = 4 \cdot 4 \cdot 4 = 64$$
2) $$14^2 = 14 \cdot 14 = 196$$
3) $$64 + 196 = 260$$
4) $$260 : 13 = 20$$
Ответ: 20
б) $$160 * 76 – 56 650 : (55+9571)$$
1) $$160 \cdot 76 = 12160$$
2) $$55+9571 = 9626$$
3) $$56650 : 9626 = 5.88509 \approx 5.89$$
4) $$12160 - 5.89 = 12154.11$$
Ответ: 12154.11
