Write a program to find squre root ?

Question

Without using sqrt() in python

Answer 1

A root of a number is just x**(1÷2), where x is the number you want to find the square root of, so using that would return the same thing as sqrt(x)

Answer 2

C, C++ do have a function called pow defined in the math library.

For others you can write an exp function to do the same. Exponentiation being iterated multiplication. 2^3 = 2*2*2

For (n^m) Using a for loop which runs m times and multiplies n by a result variable(r=1).

Answer 3

Here is a tutorial which explains newton's method:

Answer 4

Werg Serium I don't know, but he can ask us if not.
I think Faisals method is much easier ;)

Answer 5

Denise the question is, can he put the newton's method into code?

Answer 6

Yes it is Denise. The Faisal method is the simplest ones. No need of hard maths xD

Answer 7

But this is only possible because in python there is an exponential operator **. If you try java, c or c++, there is no way if you did not use newton's method.
