La 8 y 9

Answer 1

8.

a) abc = (1)(2)(- 3) = - 6

b) b²pq = (2)²(- 2)(1) = (4)(- 2) = - 8

c) 3acq = 3(1)(- 3)(1) = (3)(- 3) = - 9

d) b²cp³ = (2)²(- 3)(- 2)³ = (4)(- 3)(- 8) = 96

e) bp³q² = (2)(- 2)³(1)² = (2)(- 8) = - 16

f) - 4abc = - 4(1)(2)(- 3) = 24

9.

P(- 3) = 2(- 3)⁴ - 3(- 3)² - 5(- 3) + 11

P(- 3) = 2(81) - 3(9) + 15 + 11

P(- 3) = 162 - 27 + 15

P(- 3) = 150

P(2) = 2(2)⁴ - 3(2)² - 5(2) + 11

P(2) = 2(16) - 3(4) - 10 + 11

P(2) = 32 - 12 + 1

P(2) = 21

E = 2P(- 3) - 3P(2)

E = 2(150) - 3(21)

E = 300 - 63

E = 237
