Explicație pas cu pas:

$4¹⁴ - (6 \times 4¹³ - 2 \times 2²⁶) = {2}^{28} - (2 \times 3 \times {2}^{26} - {2}^{27}) = {2}^{28} - (3 \times {2}^{27} - {2}^{27} ) = {2}^{28} - {2}^{27} (3 - 1 ) = {2}^{28} - {2}^{28} = 0$

Answer 2

Răspuns:

4¹⁴-(6•4¹³-2•2²⁶)​=

(2²)¹⁴-[2·3·(2²)¹³-2¹⁺²⁶]=

2²⁸-(2²⁷·3-2²⁷)=

2²⁸-2²⁷(3-1)=

2²⁸-2²⁷·2=
