64= 8^2
121=11^2
10000= 100^2
11^4 = (11^2)^2
21^17 : 21^13 = 21^4 = (21^2)^2
17^13 x 17^19 = 17^32 = (17^16)^2
(7^3)^6 = 7^18 = (7^9)^2
2^8 x 4^3 x (1625/100)^17 = (2^4)^2 x (2^2)^3 x ... asta-i scris gresit, daca era 6,25 era ok dar ai scris 16,25 si nu merge asa...
36^7 : 6^8 = (6^2)^7 : 6^8 = 6^(14-8) = 6^6 = (6^3)^2
2^35 + 2^35 = 2x2^35 = 2^36 = (2^18)^2
Gata, asta este. Succes in continuare!
