Follow the pattern backwards:
* x³= x*x*x divide by x is x²
* x² = x*x divide by x is x
* x¹= x divide by x (x/x) is 1 : Follow the index law
* x^(0) = 1 divide by x is x^(-1) (x/x/x , 1/x)
When an operation inverts on itself, it negates itself into 1 and further increases it’s inverse operation. You are thinking of dividing by 0 which has no value therefore it cannot be calculated.
