Explicație pas cu pas:
2^9 + 2^9 = 2*2^9 = 2^10 = (2^5)^2
___________
2^11 + 2^11 = 2*2^11 = 2^12 = (2^6)^2
___________
3^7 + 3^7 + 3^7 = 3*3^7 = 3^8 = (3^4)^2
___________
3^6 + 3^7 = 3^6*(1 + 3) = 4*3^6 = 2^2*3^6 = (2*3^3)^2
___________
5^9 - 5^8 = 5^8*(5 - 1) = 4*5^8 = 2^2*5^8 = (2*5^4)^2
___________
8^5*2^7 = (2^3)^5*2^7 = 2^15*2^7 = 2^22 = (2^11)^2
___________
5^7*25^3 : 5 = 5^6*(5^2)^3 = 5^6*5^6 = 5^12 = (5^6)^2
___________
3^11 + 9^5 = 3^11 + (3^2)^5 = 3^11 + 3^10 = 3^10*(3 + 1) = 4*3^10 = 2^2*3^10
= (2*3^5)^2
___________
(27^3)^5 : 3^19 = 27^15 : 3^19 = (3^3)^15 : 3^19 = 3^45 : 3^19 = 3^26 = (3^13)^2
___________
5^9 + 4*5^8 = 5^8*(5 + 4) = 9*5^8 = 3^2*5^8 = (3*5^4)^2
___________
3^10 - 3^9 - 2*3^8 = 3^8*(3^2 - 3 - 2) = 3^8*(9 - 3 - 2) = 4*3^8 = 2^2*3^8
= (2*3^4)^2
___________
10^15 : 2^15 *125 = 2^15*5^15 : 2^15*5^3 = 5^15*5^3 = 5^18 = (5^9)^2
