Answer 1

Răspuns:

• $\color{red} \boxed{ \: - 44}$

Explicație pas cu pas:

❁ Salut! ❁

$\bf ➾ \: {(- 2)}^{2019} \div {2}^{2017} - 10 \times ( - 2 - 2 \times (( { - 4}^{5} ) \div {4}^{5} - 2))$

$\bf ➾ \: { - 2}^{2019} \div {2}^{2017} - 10 \times ( - 2 - 2 \times ( - 1 - 2))$

$\bf ➾ \: { - 2}^{2019} \div {2}^{2017} - 10 \times ( - 2 - 2 \times ( - 3))$

$\bf ➾ \: { - 2}^{2019} \div {2}^{2017} - 10 \times ( - 2 + 6)$

$\bf ➾ \: { - 2}^{2019} \div {2}^{2017} - 10 \times 4$

$\bf ➾ \: { - 2}^{2} - 10 \times 4$

$\bf ➾ \: - 4 - 10 \times 4$

$\bf ➾ \: - 4 - 40$

$➾\: \boxed{ \bf \: - 44}$

Succes! ☺️
