Yang bisa, tolong bantu jawab Tolong yaa..

a) m/3 × m/3 × m/3
= m³/27

b) m/n × 2m/3n ÷ 9n/4m²
= 2m²/3n² × 4m²/9n
= 8m⁴/27n³

c) 2ab/3c ÷ 6a³b/9c²d ÷ b³a/d²c
= 2ab/3c × 9c²d/6a³b × d²c/b³a
= 3cd/3a²b × d²c/b³a
= c²d³/a³b⁴

d) a³b/c²d × 2c/4a²b ÷ 4d³/8a² × ab/cd
= 2a/cd ÷ bd²/2a
= 2a/cd × 2a/bd²
= 4a²/bcd³
