Use the four numbers 1, 2, 3 and 4 to form two two digit numbers respectively, so as to maximize the product of the two two digit numbers. What are the two two digit numbers?

Use 1, 2, 3 and 4 to form two two digit numbers, so that the product of the two two digit numbers is the largest, then the two two digit numbers are 32 * 41 = 1312, because 42 * 31 = 1302 12 * 34 = 40812 * 43 = 516 13 * 42 = 54613 * 24 = 312 14 * 32 = 44814 * 23 = 322 21 * 34 = 71421 * 43 = 903 23 * 41 = 94323 * 14
