Question

alcule o valor das expressões:

a) 35 + 5²​ =

b) -18 + 10²​ =

c) -12 - 1 ⁶ =

d) 50 - 4²​ =

e) -6²​ + 20=

f) -2⁵ - 20 =

Answer 1

a) 35 + 5² =

35 + (5×5) =

35 + 25 = 60

b) -18 + 10² =

- 18 + (10×10) =

- 18 + 100 = 82

c) -12 - 1 ⁶ =

- 12 - (1×1×1×1×1) =

- 12 - 1 = - 13

d) 50 - 4² =

50 - (4×4) =

50 - 16 = 34

e) -6² + 20=

- (6×6) + 20 =

- 36 + 20 = - 16

f) -2⁵ - 20 =

- (2×2×2×2×2) - 20 =

- 32 - 20 = - 52
