10 distinct letters and the digits 0 to 9.
In the set of equations below both str1 and str2
are strings of 4 digits:
sqrt(str1 str2) = chit
sqrt(str2 str1) = cash
If 10265102493 is a valid English word, how much
( complying with the puzzle's coding) is q*z ?
Rem: sqrt(str1 str2) is a square root of an 8 digit number represented by a concatenation of the strings in the brackets.
