2 absent digits (Posted on 2020-11-28) Difficulty: 2 of 5
The product of 722*227 (163,894) contains neither 2 nor 7. List all the couples (b,c; b>c) such that the product bcc*ccb contains neither b nor c. Bonus: From the above list select couples, if any, using none of the corresponding digits in the partial products as well.
