Question

Calcule o valor de cada uma das expressões

a) A = (3^4)^2(-2)^3+(-1^2)^1

b) b = (1)^-2+(1^2)^-2+(1^3)^-1

Answer 1

A)  

(3³)²(-2)³+(-1²)¹
(3^6)(-8)+(-1²)
(729)(-8)+1
-5,832+1
=5,831

B)

(1)^-2+(1²)^-2+(1³)^-1

(1/1)^2+1^-4+1^-3
1²/1²  + (1/1)^4 + (1/1)^3
1^2/1^2 +  1^4/1^4  +  1^3/1^3
1/1 + 1/1 + 1/1
=1+1+1=3
