Salut !
Am sa iti fac 2-3 exercitii pentru a intelege metoda de rezolvare.
13⁷ =
= 13⁶ₓ13
= (13³)²ₓ(9 + 4)
= (13³)²(3² + 2²)
= (13³)²ₓ3² + (13³)²ₓ2²
= (13³ₓ3)² + (13³ₓ2)²
65¹³ =
= 65¹²ₓ65
= (65⁶)²ₓ(64 + 1)
= (65⁶)²ₓ(8² + 1²)
= (65⁶)²ₓ8² + (65⁶)²ₓ1²
= (65⁶ₓ8)² + (65⁶)²
29³¹ =
= 29³⁰ₓ29
= (29¹⁵)²ₓ(25 + 4)
= (29¹⁵)²ₓ(5² + 2²)
= (29¹⁵)²ₓ5² + (29¹⁵)²ₓ2²
= (29¹⁵ₓ5)² + (29¹⁵ₓ2)²
Bafta !
