1. 4a (5a – b) + a (2a + b)
2. -2a (3a + b) + 5a²b + 10 a³ + 6 ab²
3. 3 x³ (zx²y – 3xy⁴)
4. 3x²y : x²y³
5. (-5 × y4z) (zx²y) (3x³z²)
——————————————–
5 × y²
Jawablah pertanyaan berikut!!
1) 20a² – 20ab + 2a² + ab => 22a² – 19ab
2) -6a² – 2ab + 5a²b + 10a³ + 6ab²
3) 3x⁵yz – 9x⁴y⁴
4) 3x²y/x²y³ = 3
y²
5) (-5 × y4z) (zx²y) (3x³z²) = ………………………..
