1014. Виконайте дії:

1) 4712 ∙ (–1311) – (–1115) ∙ (–4564) = 5512 ∙ (–1411) – 1615 ∙ 4564 = – 356 – 34 = –51012 – 912 = –51912 = –6712;

2) – 8188 ∙ (–6 + (–11315) ∙ (–11921)) = – 8188 ∙ (–6 + 2815 ∙ 4021) = –8188 ∙ (–6 + 329) = – 8188 ∙ (–6 + 359) = – 8188 ∙ (–249) = – 8188 ∙ (–229) = 94 = 214;

3) (–45 – 47) ∙ (579 – 71112) = – 4835 ∙ (52836 – 73336) = – 4835 ∙ (–2536) = 4836 ∙ 7736 = 4415 = 21415;

4) (– 1118 + (–229) ∙ (–0,2))³ ∙ (–1,2) = (–1118 + 209 ∙ 15)³ ∙ (–65) = (–1118 + 49)³ ∙ (–65) = (–16)³ ∙ (–65) = – 1216 ∙ (–65) = 1180.
