Answer 1

Răspuns:

Sa vedem daca am inteles:

  3³ + 3¹⁰ : 3⁸ × 3 + 3 × 3⁷ : 3⁵ + 2 × 3¹⁰ : (5 × 3⁵ + 3⁵) + 9 × 3³ = ​

= 3³ + 3² × 3 + 3⁸ : 3⁵ + 2 × 3¹⁰ : 3⁵ × (5 + 1) + 3² × 3³ = ​

= 3³ + 3³ + 3³ + 2 × 3⁵ × 6 + 3⁵ = ​

= 3 × 3³ + 12 × 3⁵ + 3⁵ = ​

= 3⁴ + 3⁵ × (12 + 1) = ​

= 3⁴ + 3⁵ × 13 = ​

= 3⁴ × (1 + 3 × 13) = ​

= 3⁴ × (1 + 39) = ​

= 3⁴ × 40 = ​

= 81 × 40 =

= 3 240
