Krypto#2[√x, √2x, √6x]
The encryption key tells you how the digits in the grid have been encoded.
To correctly fill in the empty cells, first decrypt the numbers (that is, use the inverse of the encryption key) to find the correct digit for each position.
Next, apply the standard sudoku rules: compare digits in rows, columns, and 3×3 boxes to eliminate impossible options and determine the correct number.
The next step is to re-encrypt the chosen digit — in other words, substitute it into the formula (the part of the key assigned to that module) and then write the resulting value into the grid. This value may be a square root or a simple number if the expression simplifies.
Finally, fill the entire grid so that it is encoded exactly according to the same encryption key as the starting puzzle — except now all cells are completed.

How to Solve SudokuCrypto #2
Select the correct vertical module (3 columns).
Decrypt the cell by using the inverse of the encryption key.
Apply the standard sudoku rules to find the correct digit for that position.
Encrypt the chosen digit (according to the key for that module) and write its form in the grid — this may be a square root expression or a regular number if the expression simplifies.
Repeat these steps until the entire grid is filled with the encoded values.
