Answer 1

Răspuns:

Explicație pas cu pas:

a. (158 - 12²) × (8²+6²)= (158-144) x (48+36) = 14 * 84 = 1176

b. 1²⁰⁴ + 205¹ + 206⁰ + 0²⁰⁷ = 1+205+1+0=207

c. (5²)³⁰ × 5¹⁸ : 5⁷⁸ + (3²)³= 5⁶⁰ x 5¹⁸ : 5⁷⁸ + 3⁶ = 5⁷⁸ : 5⁷⁸ + 3⁶ = 1+3⁶= 1+729=730

d. 4¹⁸ : (2²)¹⁸ + 25¹⁰ : 5²⁰= 2³⁶ : 2³⁶ + (5²)¹⁰ : 5²⁰ = 1 + 1 = 2
