Most programming languages provide an sqrt function. Otherwise, you can just [google]

ok, do the mclauren series then.

f(x) = x^(1/2)
f`(x) = +(1/2)x^(-1/2)
f(2)(x)= -(1/4)x^(-3/2)
f(3)(x)= +(1/8)x^(-5/2)

.. plug in 0 for x, and then do out the mclauren series and your good

also, newton's binomial series is good
also, you can use any non linear solver you want, like newtons method or bisection method.
