ohayou^^ mohon bantu ya jawab yaa! Kalo bisa pake caranya yaa^^ Arigatou!!(∩_∩)

1.a.(-2/5)^-4 =( -5/2)^4 = 625/16

b.(-3/2)^-5 = (-2/3)^5 = -32/243

c.(-5/6)^-3 = (6/-5)^3 = -216/125

d.(-10/3)^-4 = (-3/10)^4 = 81/10000

2.
a.(1/7a)^2 = 1/49a²

b.(3/5a)^-3 = (5a/3)^3 = 125a^3/27

c.(2/3a)^-5 = (3a/2)^5 = 243a^5/32

d.(-4/5a) = -4/5a
