a) √1/32 = 1/2^5 = 2^-5 atau 2 pangkat ngatif 5
b) 1/√(1/4)^-3 = 1/(1/4)-3/2 = 1.(4/1) -^3/2 = (4)^-3/2
= (2²)^-3/2
= 2^-3

a) (16/125) ^1/4 + (4/25)^1/2 - (8/125)^1/3
=(2^4/125)^1/4 + (2²/25)^1/2 - (2^3/125)^1/3
= 2/125 + 2/25 - 2/125
= 2/125 + 10/125 - 2/125
= 12/125 - 2/125
= 10/125
= 10/125 : 5/5
= 2/25
