Answer 2

Răspuns:

$\it a = (( - 2)^{4} \div 4 - ( - 2) ^{42} \div ( - 2) ^{40} ) \times ( - 200) - 5 \\ \\ \it \ a = ( 2^{4} \div {2}^{2} - ( - 2) ^{42 - 40} ) \times ( - 200) - 5 \\ \\ \it \ \ a = ({2}^{4 - 2} - ( - 2)^{2}) \times ( - 200) - 5 \\ \\ \it \ a = ({2}^{2} - {2}^{2} ) \times ( - 200) - 5 \\ \\ \it \ \ a = (4 - 4) \times ( - 200) - 5 \\ \\ \it \ \ a = 0 \times ( - 200) - 5 \\ \\ \boxed{ \it \ \ a = - 5}$

a = | -5 | = 5
