Answer 1

Explicação passo-a-passo:

$b) \: (38 {z}^{3} + 8 {x}^{3} + 45) + (39 {z}^{3} + 13x + 6) \\ 38 {z}^{3} + 8 {x}^{3} + 45 + 39 {z}^{3} + 13x + 6 \\ 77 {z}^{3} + 8 {x}^{3} + 13x + 51$

$c) \: (72 {y}^{6} + 21 {y}^{7} + 2 {y}^{2} ) - (31 {y}^{6} + 13 {y}^{7} + {y}^{2} ) \\ 72 {y}^{6} + 21 {y}^{7} + 2 {y}^{2} - 31 {y}^{6} - 13 {y}^{7} - {y}^{2} \\ 41 {y}^{6} + 8 {y}^{7} + {y}^{2} \\ 8 {y}^{7} + 41 {y}^{6} + {y}^{2}$

$d) \: (54 {x}^{2} + 12x) - (36 {x}^{2} + 11x + 4) \\ 54 {x}^{2} + 12x - 36 {x}^{2} - 11x - 4 \\ 18 {x}^{2} + x - 4$

$e) \: (3 {x}^{2}) \times (5 {x}^{2} + 5) \\ 15 {x}^{4} + 15 {x}^{2}$

$f) \: ( {2y}^{6} + 2x) \times (3 {x}^{2} + 2y) \\ 6 {x}^{2} {y}^{6} + 4 {y}^{7} + 6 {x}^{3} + 4xy$

$g) \: (8 {z}^{2} ) \times (4 {z}^{6} + 15 {z}^{3} ) \\ 32 {z}^{8} + 120 {z}^{5}$
