Помогите, пожалуйста)))к

Решите задачу:

$a) \: 5 {x}^{0} = |x = 16| = 5 \times ( {16})^{0} = 5 \times 1 = 5$
$b) \: - 3 {x}^{0} = |x = - 2| = - 3 \times ( { - 2})^{0} = - 3 \times 1 = - 3$
$v) \: 5 {a}^{0} - {a}^{3} = |a = 2| = 5 \times ( {2})^{0} - ({2})^{3} = 5 \times 1 - 8 = - 3$
$g) \: 4 {a}^{3} - 2 {a}^{0} = |a = - 3| = 4 \times ( { - 3})^{3} - 2 \times ( { - 3})^{0} = 4 \times ( - 27) - 2 \times 1 = - 110$
