Question

[(-2)x(+4)]²:(2³)+[(-32):(+16)]³

Answer 1

[(-2)x(4)] x^{2} :[(-32):(16)] x^{3} 
[-8] x^{2} :[-2]x^{3} 
(-8)x(-8):(-8)
-8

Answer 2

$\frac{ { (- 2 \times 4)}^{2} }{ {2}^{3} } + \frac{( { - 32}^{3} )}{ {16}^{3} } = \\ \frac{ { - 2}^{6} }{ {2}^{3} } - \frac{ { - 2}^{15} }{ {2}^{12} } = \\ { - 2}^{3} - ( { - 2}^{3)} = \\ - {2}^{3} + {2}^{3} = \\ \\ 8 - 8 = 0$
