To find the units digit of (29^{57}), we can focus on the units digit of the base, which is 9. The units digits of powers of 9 follow a pattern: (9^1 = 9), (9^2 = 81) (units digit 1), (9^3 = 729) (units digit 9), and (9^4 = 6561) (units digit 1). This pattern alternates between 9 and 1. Since (57) is odd, the units digit of (29^{57}) is the same as that of (9^{57}), which is (9). Thus, the units digit of (29^{57}) is (9).
Let the ones digit be represented as ( x ). Since the ten digit is 9 more than the ones digit, it can be expressed as ( x + 9 ). However, since digits can only range from 0 to 9, the only solution is when the ones digit ( x ) is 0, making the ten digit 9. Therefore, the two-digit number is 90.
