me ajudem ? resolver

a) (-1)³-(-1)⁴+(-2)²-2³+(-1+)²


b) 5.(64-12:4)

​

Answer 1

a) (-1)³-(-1)⁴+(-2)²-2³+(-1+)² =

-1-(4)+(4)-8+(1)=

-1-4+4-8+1=

-13+5=

- 8

b) 5.(64-12:4) =

5(64-3)=

5(61) =

305

Answer 2

$a)( - 1) {}^{3} - ( - 1) {}^{4} + ( - 2) {}^{2} - 2 {}^{2} + ( - 1) {}^{2} \\ - 1 - 1 + 4 - 8 + 1 = - 10 + 5 = - 5 \\ \\ b)5(64 - \frac{12}{4} ) \\ 5(64 - \frac{3}{1} ) \\ 5(61) = 305$
