(4^-2 x 4^5) : (4^-8 : 4^4 ) x (4^-3)^5= 4^__ =___

błagam o uzupełnienie luk ;) bedzie naj .

Answer 1

(-3)^-4 : (-3)^-8 = (-3) ^ 4 = 81

(-1,5)^8 : (-1,5)^10 = (-1,5)^ -2 = 4/9

((1 2/3 )^-2)2 = (1 2/3)^ -4 = (3/5)^4 = 81/625

 

(4^-2 x 4^5) : (4^-8 : 4^4 ) x (4^-3)^5= 4^3 : 4^-12 x 4^-15= 4^0=1
