Explicație pas cu pas:
125 × 1111³ - 5555³ = 5³ × 1111³- (5 × 1111)³ =
5³ × 1111³- 5³ × 1111³ = 0

9⁵ - (3⁵)² + 8⁴ - (2⁴)³ =
(3²)⁵ - 3⁵ˣ² + (2³)⁴ - 2⁴ˣ³ =
3⁵ˣ² - 3¹⁰ + 2³ˣ⁴ - 2¹² =
3¹⁰ - 3¹⁰ + 2¹² - 2¹² = 0
2⁷ : 4³ + 3³ × 3³ : 3⁵ + (3 × 2⁴ - 4²) : 2³ =
2⁷ : (2²)³ + 3³ × 3³ : 3⁵ + [3 × 2⁴ - (2²)²] : 2³ =
2⁷ : 2²ˣ³ + 3³⁺³⁻⁵ + (3 × 2⁴ - 2²ˣ²) : 2³ =
2⁷ : 2⁶ + 3¹ + (3 × 2⁴ - 2⁴) : 2³ =
2⁷⁻⁶ + 3¹ + 2⁴ × (3 × 2⁴⁻⁴ - 2⁴⁻⁴) : 2³ =
2¹ + 3¹ + 2⁴ × (3 × 2⁰ - 2⁰) : 2³ =
2 + 3 + 2⁴ × (3 × 1 - 1) : 2³ =
2 + 3 + 2⁴ × (3 - 1) : 2³ =
2 + 3 + 2⁴ × 2 : 2³ =
2 + 3 + 2⁴⁺¹⁻³ =
2 + 3 + 2² =
2 + 3 + 4 = 9
