Answer 2

Let's solve each equation step by step:

1. 13 + (-3³) = 7 • (-2) 13 + (-27) = 7 • (-2) -14 = -14 This equation is true.

2. 2³ - 13 = 6 : (-1,2) 8 - 13 = 6 / (-1,2) -5 = -3 (No real solution for this equation)

3. (-7)² - 30 = 4² + 3 49 - 30 = 16 + 3 19 = 19 This equation is true.

4. 51 - 10² = (-4)³ + 15 51 - 100 = (-64) + 15 -49 = -49 This equation is true.

5. (-2)⁵ + (-4)² = 80 : (-5) -32 + 16 = 80 / (-5) -16 = -16 This equation is true.

6. 84 : (-7) = (-5)² - 37 -12 = 25 - 37 -12 = -12 This equation is true.

All of the equations are true, except for the second one, which has no real solution.
