Question

Calcule o valor da expressao (a³-b²)×+2 quando a = -2, b= -3 e x= -4

Answer 1

[-8-(-9)]^-4 + 2
(-8+9)^-4 +2
1^-4+2
1+2 = 3

Answer 2

Resposta:

(a³ - b²)^(x + 2)

 

com a = -2 , b = -3, x = -4

a³ = (-2)³ = -8

b² = (-3)² = 9

a³ - b² = -8 - 9 = -17  

x + 2 = -4 + 2 = -2

(-17)^-2 = (1/17)² = 1/289
