TATAP2004 · Answer

(3⁵/₆ - 1²/₁₅) × ⁵/₉ + ((¹/₂₀ + 0,24) × 8¹/₃ - 1¹/₆) × 2 = 4

1) 3⁵/₆ - 1²/₁₅ = ²³/₆ - ¹⁷/₁₅ = ²³ˣ⁵/₃₀ - ¹⁷ˣ²/₃₀ = ¹¹⁵/₃₀ - ³⁴/₃₀ = ⁸¹/₃₀
2) ⁸¹/₃₀ × ⁵/₉ = ⁸¹ˣ⁵/₃₀ₓ₉ = ⁹ˣ¹/₆ₓ₁ = ⁹/₆ = ³/₂
3) ¹/₂₀ + 0,24 = ¹/₂₀ + ²⁴/₁₀₀ = ¹ˣ⁵/₁₀₀ + ²⁴/₁₀₀ = ²⁹/₁₀₀
4) ²⁹/₁₀₀ × 8¹/₃ = ²⁹/₁₀₀ × ²⁵/₃ = ²⁹ˣ²⁵/₃ₓ₁₀₀ = ²⁹/₃ₓ₄ = ²⁹/₁₂
5) ²⁹/₁₂ - 1¹/₆ = ²⁹/₁₂ - ⁷/₆ = ²⁹/₁₂ - ⁷ˣ²/₁₂ = ²⁹/₁₂ - ¹⁴/₁₂ = ²⁹⁻¹⁴/₁₂ = ¹⁵/₁₂ = ⁵/₄
6) ⁵/₄ × 2 = ⁵/₄ × ²/₁ = ⁵ˣ²/₄ₓ₁ = ¹⁰/₄ = ⁵/₂
7) ³/₂ + ⁵/₂ = ³⁺⁵/₂ = ⁸/₂ = 4
