Answer 1

a) 54 - (2 × 4^4 - 18²) : 47 + 5³ : (4 + 3 × 7) - 5 × 3² =

54 - (256 - 324) : 47 + 125 : 25 - 5 × 9 =

54 - (- 68) : 47 + 5 - 45 =

54 + 1,4 - 40 =

8,6

b) {(3^4 - 2^4 × 5)^5 - [6² - (7 × 5²) : 5]³} : 2³ =

{(3^9 - 2^9 × 5^5) - [6^5 -(7³ × 5^5) : 5³} : 8 =

{(19.683 - 1.024 × 3.125) - [7.776 -(343 ×3.125) : 125} : 8 =

{(19.683 - 3.200.000) - [7.776 - 1.071.875] : 125} : 8 =

{-3.180.317 - 1.064.099 : 125} : 8 =

{-3.180.317 - 8.512,792} : 8 =

- 31.888.229,792 : 8 =

- 398.603,724

c) 2^10 - (8² × 8) + (5³ × 5) - {(784 - 7²) + 9² - 3³} =

2.048 - 512 + 625 -{(784 - 49) + 81 -81} =

2.161 - 735 =

1.426
