Sederhanakan dan tuliskan jawabannya dalam bentuk pang kat positif. tolong di jawab yaaa perlu bsk dikumpul

f. (2ab^-3)^-2= (2^-2)(a^-2)(b^6) = (1/4)(1/a^2)(b^6)= b^6/4a^2
g. (2x^-1/y)^2 = (2^2)(x^-2)/y^2 = 4(1/x^2)/y^2 = 4/x^2y^2
h. (4m/n^-3)^2 = (4^2)(m^2)/(n^-6) = (16m^2)/(1/n^6) = 16m^2 × n^6 = 16m^3n^6
i. (6a^-4/c^-3)^-2 = (6^2)(a^8)/(c^6) = 36a^8/c^6
j. (5x/y^-4)^-3 = (5^-3)(x^-3)/(y^12) = 1/125 (1/x^3) / y^12 = 1/125x^3 / y^12 = y^12/125x^3

semoga membantu.......
maaf kalo salah.....
