You can look that up and see it will find the square root of any number. 1.77. The sqare root of pie is about 1.7724538509055. pi= ABOUT 3.14 Pi is an irrational number, that is it has an infinite number of digits after the decimal point. Therefore its squre root would also be irrational. However you can come as close as you with depending on how accurate you need the answer.
Since 13 is not a square number there is no exact real answer, but you can find an approximate value using the following (Newton-Raphson) iteration formula: xn+1=x n - (x2n -13)/(2xn). Using this formula the square root of 13 can be stated as 3.605551275 to 10 s.f. after 3 iterations starting from 3.5.
