(1/5 . 3/9)² + √9/4 - 1/2 + (2/3)² =
(3/45)² + 3/2 - 1/2 + 2²/3² =
3²/45² + 3/2 - 1/2 + 4/9
9/2025 + 3/2 - 1/2 + 4/9
Sacas el mcm de los denominadores, para ello descompones
2025 2 2 9 2(mita)
2025 1 1 9 3(tercera)

El mcm de 20250, 2 y 9 = 2 * 3 * 3 * 3 * 3 * 3 * 5 * 5 = 12150
9/2025 + 3/2 - 1/2 + 4/9 =
9 + 3*6075 - 6075 + 4*1350
--------------------------------------- =
