Răspuns:

Explicație pas cu pas:

a)

32 = 2^5

243 = 3^5

(2/3)^x = 32/243 = 2^5/3^5 = (2/3)^5

x = 5

b)

225/100 = 9/4 = 3^2/2^2 = (3/2)^2

(3/2)^x = (3/2)^2

x = 2

c)

2/98 = 1/49 = = 1^2/7^2 =  (1/7)^2

(1/7)^x = (1/7)^2

x = 2

d)

125/50 = 5/2

125/8 = 5^3/2^3 = (5/2)^3

(5/2)^x = (5/2)^3

x = 3
