care ma ajuta va rog frumsssss dau coroana ma jur pe ce vreti voi va rog multttttt​ repedeee cat de repede posibil

Răspuns:

Explicație pas cu pas:

ai doar de scazut exponentii

2^25 : 2^15 = 2^10

3^12 : 3 = 3^12 : 3^1 = 3^11

7^14 : 7^14 = 7^0 = 1

12^40 : 12^37 = 12^3

a^112 : a^92 = a^20

13^n+1 : 13^n = 13^1 = 13
