Răspuns:

a) 0,9^5 * 0.9^3 = 0.9^8

Explicatie: 0,9^5 * 0.9^3 = 0.9^5+3

b) (2/3)^5 * 4/9 = (2/3)^7

Explicatie: (2/3)^5 * (2/3)^2 = (2/3)^7

c) (-6,11)^-11 : 6,11^10 = (-6,11)^-21

Explicatie: (-6,11)^-11 : 6,11^10 = (-6,11)^-11-10

d) 9/25 : (3/5)^-1 = (3/5)^3

Explicatie: (3/5)^2 : (3/5)^-1 = (3/5)^3

e) |-3/5|^2 * (-3/5)^3 = -(3/5)^5

Explicatie: |-3/5|^2 * (-3/5)^3 = -(3/5)^2+3
