Explicație pas cu pas:
27^7 : 9^2 = (3^3)^7 : (3^2)^2 = 3^21 : 3^4 = 3^17
3^2n-3 = 3^17
2n - 3 = 17
2n = 17 + 3 = 20
n = 20 : 2 = 10

25^11 = (5^2)^11 = 5^22
5^3n+1 = 5^22
3n + 1 = 22
3n = 22 - 1 = 21
n = 21 : 3 = 7
_________________
49^2^3 = 49^8 = (7^2)^8 = 7^16
7^n+1 : 7^4 = 7^n+1-4 = 7^n-3
7^n-3 = 7^16
n - 3 = 16
n = 16 + 3 = 19

10^2n+1 = (2*5)^2n+1 = 2^2n+1*5^2n+1
2^2n+1*5^2n+1 : 5^2n+1 = 2^2n+1
8^9 = (2^3)^9 = 2^27
2^2n+1 = 2^27
2n + 1 = 27
2n = 27 - 1 = 26
n = 26 : 2 = 13
