● Calculation;
[tex]a = ( - 2) ^{3} [/tex]
[tex]a = ( - 2) \times ( - 2 \times ( - 2)[/tex]
[tex] \: \boxed{a = -8} [/tex]
[tex]------------------[/tex]
[tex]b = ( + 2) {}^{3} [/tex]
[tex]b = 2 \times 2 \times 2[/tex]
[tex] \: \boxed{b = 8} [/tex]
[tex]------------------[/tex]
[tex]a - b[/tex]
[tex] - 8 - 8[/tex]
[tex] \: \boxed{-16} [/tex]
