pake caranya yaa mohon

(9^-3/2 . 3 + 27^-1) / (27^-4/3 + 81^-3/4)
= (3^2(-3/2) . 3 + 1/27) / (3^3(-4/3) + 3^4(-3/4))
= (3^-3 . 3 + 1/27) / (3^-4 + 3^-3)
= (3/3^3 + 1/27) / (1/3^4 + 1/3^3)
= (3/27 + 1/27) / (1/81 + 1/27)
= (4/27) / (4/81)
= 4/27 . 81/4
= 81/27
= 3

=(3/27 + 1/27) / (1/81 + 1/27)
=(4/27) / (4/81)
=4/27 . 81/4
=81/27
B. 3
