Răspuns:
Explicație pas cu pas:
a)
(3/7)^3 * (3/7)^5 : (3/7)^6 = (3/7)^8 : (3/7)^6 = (3/7)^2
b)
[(3/7)^3]^4 : (3/7)^10 = (3/7)^12 : (3/7)^10 = (3/7)^2
c)
[(3/7)^9]^3 : [(3/7)^4]^6 = (3/7)^27 : (3/7)^24 = (3/7)^3
d)
(3/7)^9 : (3/7)^6 = (3/7)^3
e)
(3/7)^32 : (3/7)^25 = (3/7)^7
f)
81/2401 = 3^4/7^4 = (3/7)^4
[(3/7)^4]^2 : (3/7)^3 : (3/7) = (3/7)^8 : (3/7)^3 : (3/7) = (3/7)^5 : (3/7) = (3/7)^4
