1) Преобразуйте многочлен к стандартному виду: a) 8d + d – 6; b) h + 2h² – 3h³; c) 7x – x + 6; d) k ⋅ k⁵ ⋅ 9.

a) 8d + d – 6 = (8+1)d – 6 = 9d - 6 Ответ: $$9d-6$$ b) h + 2h² – 3h³ Ответ: $$h + 2h² – 3h³$$ c) 7x – x + 6 = (7-1)x + 6 = 6x + 6 Ответ: $$6x+6$$ d) k ⋅ k⁵ ⋅ 9 = 9 ⋅ k^(1+5) = 9k⁶ Ответ: $$9k^6$$
