Question

hola alguien que me ayude

Answer 1

{x}^{3} + 5x - 13 - 4 {x}^{2}

{- 2}^{3} + 5(- 2) - 13 - 4 {- 2}^{2}

- 8 - 10 - 13 - 4 (4)

- 18 - 13 - 16

- 47

{x}^{3} + 5x {y}^{2} - 8 {y}^{3}

{- 2}^{3} + 5(- 2) {5}^{2} - 8 {5}^{3}

- 8 + 5(- 2) (25) - 8 (125)

- 8 + 5 (- 50) - 1000

- 8 - 250 - 1000

- 1258

{- y}^{4} + {x}^{4}

{x}^{4} - {y}^{4}

{- 2}^{4} - {5}^{4}

16 - 625

- 609

{x}^{3} + {y}^{3} + 3 {x}^{2}y + 3x{y}^{2}

{-2}^{3} + {5}^{3} + 3 {-2}^{2}(5) + 3(-2){5}^{2}

-8 + 125 + 3 (4)(5) + 3(-2)(25)

-8 + 125 + 3 (20) + 3 (-50)

-8 + 125 + 60 - 150

117 - 90

27

1 {x}^{3} - 3 {y}^{3} + 1 x{y}^{2}

2 9

1 {-2}^{3} - 3 {5}^{3} + 1 (-2){5}^{2}

2 9

1 (-8) - 3 (125) + 1 (-2)(25)

2 9

- 8 - 375 + 1 (-50)

2 9

- 8 - 375 - 50

2 9

- 4 - 375 - 50

9

- 379 - 50 /÷9
