Răspuns :

2^29 • (2^2 + 2 + 1) = x • 2^28
2^29 • 7 = x • 2^28
x = (2^29 • 7)/2^28
x = 2 • 7
x = 14

Răspuns:

2³¹ + 2³⁰ + 2²⁹ = x • 2²⁸

= (2² + 2 +1) • 2²⁹ = x • 2²⁸

= ( 2² + 2 +1 ) • 2²⁹ = 2²⁸ • x

= (4 + 2 + 1 ) • 2²⁹ = 2²⁸ • x

= 7 • 2²⁹ = 2²⁸ • x

= x = 7 • 2²⁹: 2²⁸

= x = 7 • 2²⁹‐²⁸

= x = 7 • 2¹ => x = 7 • 2 => x = 14
