176. Обчисліть:

1) 2 + 10³ + 5 • 2⁴ = 2 + 1000 + 5 • 16 = 1002 + 80 = 1082;

2) –16 • (14)² + 2⁴ = –16 • (116) + 16 = –1 + 16 = 15;

3) ((–5)³ + 5²) : 10 = (–125 + 25) : 10 = –100 : 10 = –10;

4) (–12 + 8²) : (–2) = (–12 + 64) : (–2) = 52 : (–2) = –26;

5) (–12 + (–8))² • 5 = (–20)² • 5 = 400 • 5 = 2000;

6) (–2)⁵ + 2⁵ + 1³ • 3¹ = 3.
