Using Python

1. [10 points] Square root approximation. Write your own square root approximation function using the equation Xk+1=21(Xk+Xkn) where X0=1. This equation says that the n can be found be repeatedly computing the next Xi term. The larger the number of terms used, the better the answer. Your function should take two input parameters: the number n that you want the square root of and the number of terms k to compute
