What is the difference between different ways to extract the root in Python?

📁 python, пример

Root in python can be extracted in three ways x ** 0.5 , pow (x, 0.5) , math.SQRT (x) . And for the whole with the result, also math.isqrt (x) . What is the difference between them?

p.s. For example, when checking simplicity n you need to make a cycle to a square root of n . So right?

   for  i  in   range  ( 2 ,  int  (n **  0.5 ) +  1 ): ) ...     

We are primarily about the correctness (accuracy of calculations). Performance in second place.
