Buna ziua!
Ma puteti ajuta va rog frumos?​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

1 ridicat la orice putere este egal cu 1

1^0 × 1^1 × 1^2 × ... × 1^20 = 1 × 1 × 1 × ... × 1 = 1

b)

2 + 2^2 × 3 : 6 + 2 × [2 + 2^2 × (3^2 + 2 × 5^2 : 10 - 9)^2] : 51

= 2 + 4 × 3 : 6 + 2 × [2 + 4 × (9 + 2 × 25 : 10 - 9)^2] : 51

= 2 + 12 : 6 + 2 × [2 + 4 × (9 + 50 : 10 - 9)^2] : 51

= 2 + 2 + 2 × [2 + 4 × (9 + 5 - 9)^2] : 51

= 4 + 2 × [2 + 4 × (14 - 9)^2] : 51

= 4 + 2 × (2 + 4 × 5^2) : 51

= 4 + 2 × (2 + 4 × 25) : 51

= 4 + 2 × (2 + 100) : 51

= 4 + 2 × 102 : 51

= 4 + 204 : 51

= 4 + 4 = 8
