    What about plain old x = -10?

    -10 ^ 2 = 100
    -10 ^ 3 = -1000
    -10 ^ 5 = -100000

    When all you have is an imaginary hammer, everything looks like a rotation around the imaginary unit circle.

    Explanation of maths

    x = -10, i = √-1 so i² = -1 and 10i²=-10

        The squareroot of 100 is ±10.

    Therefore i¹⁰ = ln(-1)¹⁰/pi¹⁰ = -1

    This is true but does not follow from the preceding steps, specifically finding it to be equal to -1. You can obviously find it from i²=-1 but they didn’t show that. I think they tried to equivocate this expression with the answer for eiπ which you can’t do, it doesn’t follow because eiπ and i¹⁰ = ln(-1)¹⁰/pi¹⁰ are different expressions and without external proof, could have different values.
