(x-2y)^4 beri caranya ya??

(x - 2y)⁴ = 1(x)⁴ - 4(x)³ (2y) - 6(x)² (2y)² + 4(x) (2y)³ + 1(2y)⁴
              = x⁴ - 4(x³) (2y) - 6(x²) (2y²) + 4(x) (2y³) + 2y⁴
              = x⁴ - 8x³y - 12x²y² + 8xy³ + 2y⁴

semoga membantu :))

Jawaban :
(x-2y)⁴
= ((x-2y) (x-2y)) ((x-2y) (x-2y))
= (x-4xy+4y²) (x-4xy+4y²)
= x⁴+24x²y²+16y⁴-8x³y-32xy³
