[tex]======================[/tex]

  • ❒The value of this Expression corresponds to -16 so alternative D is correct.

We can calculate separately, and then subtract between the values.

[tex]------------------[/tex]

● 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]

[tex]−−−−−−−✠−−−−−−−[/tex]
