Let's solve each equation and match them with the correct responses:

  1. Equation: \( x^3 = -64 \)
    Solution: \( x = -4 \)
    Response: -4

  2. Equation: \( x^2 = 64 \)
    Solution: \( x = 8 \) and \( x = -8 \)
    Response: +8 and -8

  3. Equation: \( x^2 = 25 \)
    Solution: \( x = 5 \) and \( x = -5 \)
    Response: +5 and -5

  4. Equation: \( x^3 = 125 \)
    Solution: \( x = 5 \)
    Response: +5

  5. Equation: \( x^2 = -16 \)
    Solution: No real solutions (as the square of a real number cannot be negative)
    Response: no real solution

Final matching would be:

  • \( x^3 = -64 \) : -4
  • \( x^2 = 64 \) : +8 and -8
  • \( x^2 = 25 \) : +5 and -5
  • \( x^3 = 125 \) : +5
  • \( x^2 = -16 \) : no real solution
