Original Note:
This technique does not work for all square-roots or other root functions. The examples here are hand-picked to work. For example: SQRT(169) = 13 SQRT(196) =14. 1+6+9=16 for both, which fails the method presented. This link contains some tricks for larger square roots. https://www.cuemath.com/algebra/square-root-tricks/
