✒️

======================

  • The correct alternative that corresponds to this numerical expression is the letter C. In other words, the answer will be 35.

To find the value of this expression, we will calculate the indicated powers, and then we will subtract and divide the indicated numbers in this expression.

 = ( {2}^{3}  -  {2})^{2}  - 18 \div ( {3}^{2}  \times 2)

 = (2 \times 2 \times 2 \times  {2})^{2}  - 18 \div ( {3}^{2}  \times 2)

 = (2 \times 2 \times 2 -  {2})^{2}  - 18 \div 3 \times 3 \times 2)

 = (8 -  {2})^{2}  - 18 \div (3 \times 3 \times 2)

 = (8 - 2)^{2}  - 18 \div (9 \times 2)

 = ( {6})^{2}  - 18 \div (18)

 = 36 - 18 \div 18

 = 36 - 1

  \: \boxed{=35}
