Step 1You can use Heron&#039;s algorithm to estimate       a   by computing some iterations of:      x          n      +      1        =      1    2        (          x      n        +          a              x        n              )  You should start with some       x    0    ≈      a   .

Step 1The digit-by-digit method used to be taught in school. The various root-finding approaches are often easier. When you are close, you can also use things like      37    =      36              37      36        =  6      1    +          1      36        ≈  6  (  1  +      1    72    )  ≈  6.083
