c) ( 4^0 : 4^-1 ) : ( 4^-1 :4-^2 )

d) ( -1^5)/ (-2)^-2 + (0,1)^-2

e) (-1/3)^2 - ( - 1/3 )^-2

me ajudeeem please me pfvvvvv​

Answer 1

b) - ( - 2 )^4 + ( - 2 )

- (16) - 2 = - 18

c) ( 4^0 : 4^-1 ) : ( 4^-1 :4-^2 )

(4)/(4) = 1

d) ( -1^5)/ (-2)^-2 + (0,1)^-2

(-1)/1/4 + 100

- 4 + 100 = 96

e) (-1/3)^2 - ( - 1/3 )^-2

1/9 - 9 = - 80/9

Bons estudos!
