Answer 1

Ответ:

а)

$6 {a}^{3} - {a}^{10} + 4 {a}^{3} + {a}^{10} - 8 {a}^{3} + a = 2 {a}^{3} + a \\ 2 {a}^{3} + a = 2 \times {( - 3)}^{3} - 3 = 2 \times ( - 27) - 3 = - 54 - 3 = - 57$

б)

$4 {x}^{6} {y}^{3} - 3 {x}^{6} {y}^{3} + 2 {x}^{2} {y}^{2} - {x}^{6} {y}^{3} - {x}^{2} {y}^{2} + y = {x}^{2} {y}^{2} + y \\ {x}^{2} {y}^{2} + y = {( - 2)}^{2} \times {( - 1)}^{2} - 1 = 4 \times 1 - 1 = 3$
