following could not be a solution to the addition problem below?
If k and p represent nonzero digits within the integers above, what is p?
If x represents the sum of all the positive threedigit numbers that can be constructed using each of the
distinct nonzero digits a, b, and c exactly once, what is the largest integer by which x must be divisible?
If a and b represent positive single digits in the correctly worked computation above, what is the value of the two digit integer ba?
For any four digit number, abcd, *abcd*= (3^{a})(5^{b})(7^{c})(11^{d}). What is the value of (n – m) if m and n are fourdigit numbers for which *m* = (3^{r})(5^{s})(7^{t})(11^{u}) and *n* = (25)(*m*)?
