Answer 1

C) 1

$= (2 \times (-1 ^ { 3 } ) \times (-1 ^ { 2 } )-(-1 ^ { 2 } ) \times -1) ^ { 5 } \\ = \left(2\left(-1\right)\left(-1^{2}\right)-\left(-1^{2}\right)\left(-1\right)\right)^{5} \\ = \left(-2\left(-1^{2}\right)-\left(-1^{2}\right)\left(-1\right)\right)^{5} \\ = \left(-2\left(-1\right)-\left(-1^{2}\right)\left(-1\right)\right)^{5} \\ = \left(2-\left(-1^{2}\right)\left(-1\right)\right)^{5} \\ = \left(2-1\right)^{5} \\ =1^{5} \\ = 1$

Bons estudos!
