   The square root of 84 is 9.16515139 to the first 8 decimal places.
   One of the easiest and best methods to implement on a computer is called Newton-Raphson - it has very little code and converges fast needing a maximum of only 42 iterations for normal ranges of numbers. The first estimate to start the iterations is usually 10, and double-length variables are necessary for high accuracy of the result. For square root the code would need the decimal fraction equivalent to 'one half', for third root or cube root use 'one third' and for fourth root or quad root use 'one fourth'.
