How to finde a squar root of a number without import any library...

Question

Square root

Answer 1

√ means the power of 1/2 :
print(4**0.5)

Answer 2

Here it is :
say it needs square root of 10
>>>10**(1.0/2)
3.1622776601683795

Reason for writing 1.0 is, it will return float value 0.5 if we write it as 1/2, it will return round off to Zero

Parenthesis is used, as exponential has higher precedence than division, we need result of division first.

With parenthesis, division will get higher precedence.
