(\(- 4 \left.\right) + \left(\right. - 3 \left.\right) + \left(\right. - 2 \left.\right) + \left(\right. - 1 \left.\right) + 0 + 1 + 2 + 3 + 4 + 5\).=6

Theo đề bài ta có \(150 \leq a \leq 200\) và \(a \in\) BC\(\left(\right. 4 , 5 , 6 \left.\right)\).

do bc (4,5,6)={0;60;120;180;360,…} nên \(a = 180\).

 \(\left(\right. - 4 \left.\right)^{2} . \left(\right. - 3 \left.\right) - \left[\right. \left(\right. - 93 \left.\right) + \left(\right. - 11 + 8 \left.\right)^{3} \left]\right.\)

\(= 16. \left(\right. - 3 \left.\right) - \left[\right. \left(\right. - 93 \left.\right) + \left(\right. - 3 \left.\right)^{3} \left]\right.\)

\(= - 48 - \left[\right. \left(\right. - 93 \left.\right) + \left(\right. - 27 \left.\right) \left]\right.\)

\(= - 48 - \left(\right. - 120 \left.\right)\)
