Question 1133317
<br>
This might be an interesting problem... but you have messed up the definition of n(d).<br>
You at first say that 3(5) means 555; but next you say 4(3) means 444.<br>
If I try to make sense out of the problem, the equation you show seems to have the sum of two 10-digit numbers being equal to a 32-digit number....
