tentukan hasil pemangkatan berikut ini ! a. (4/5) pangkat ^- 4 b. (-3/7)pangkat ^-2 c. (-2/3pq) pangkat ^-5 d. (-3a/2b) pangkat ^-3 mohon secepatnya karena

a)
(4/5)^(-4)
= (5/4)^4
= (5^4)/(4^4)
= 625/256
= 2 113/256

b)
(-3/7)^(-2)
= (-7/3)^2
= ((-7)^2)/(3^2)
= 49/9
= 5 4/9

c)
(-2/3pq)^(-5)
= (-3pq/2)^5
= ((-3pq)^5)/(2^5)
= (-243p^5q^5)/(32)
= (-243/32)p^5q^5

d)
(-3a/2b)^(-3)
= (-2b/3a)^3
= ((-2)^3b^3)/(3^3a^3)
= (-8b^3)/(27a^3)
