Answer:

39

Explanation:

First, let's make the equation clearly read:


{ - 4}^(2) - 7 * 4 * - 2 - {1}^(3)

Second, prioritize to calculate any multiplication or division, since this case is multiplication, then:


- {4}^(2) - (7 * 4 * - 2) - {1}^(3)


- {4}^(2) - (28 * - 2) - {1}^(3)


- {4}^(2) - ( - 56) - {1}^(3)

Third, settle any sign left in the equation before calculating:


- {4}^(2) + 56 - {1}^(3)

Fourth, simplify the above equation to:


- ( {4} * 4) + 56 - (1 * 1 * 1)


- 16 + 56 - 1

Answer is 39

Hope it helps. Thanks!
