  1. 1. 1/n^49 = 0 when n --> oo infinity

    2. x^2 = -64
    x = 8 i or -8 i
    if you have not covered imaginary and complex numbers there is no solution.

    3. 12 x because -12x is not a side of a square.

    4. no idea, do not have picture

    5. if x = -9 or +9
    81 + z = 103
    z = 22 agree

  2. The first one is clearly meant to be n^2 - 49 = 0
    so C is correct
