Answer 1

So to raise x to the power of a in python you just do x**a. So the first code is correct and works without any errors.....😕😕
math.pow works only in other programming languages so use just pow()

Answer 2

I guess this should be able to help

Answer 3

1. You are raising a negative number to a fractional root which gives a complex number e. g. - 1**.5

2. pow() is a built-in function, if you use pow() rather than math.pow() then it works 🙂
