Hi please i just solving this problem could you help to finish now the next question 6(1a)

Instructions: Use these instructions for the remainder of the exam. Your J-number JN := (K E 0. .9/ k E 1..8) = 00380397 Hence J1 = 0 1 2 = 0 1 3 = 3 J4 = 6 1 5 =0 16 =3 17=2 18=7 R Write the elements of every numerical set or multiset appearing in this exam in increasing order.

D NB XA Prm(x) x is prime. R Note that in a set an element may occur exactly once. Therefore, there may not be any repeated elements in any set in the above. So, if you do not have the correct sets, all your answers will be wrong. R If answers to different instances of some question on the exam contradict each other you will get a score of zero for every instance. R You will lose points for making any extraneous mark on the exam. R You may only submit complete answers to questions marked explicitly on the exam. You will lose points for unfinished work. R Separate pieces of work for any part of any problem recorded on a blank page intended for the purpose must be indexed by the index of the problem and also by numbers starting at 0 that record the order in which the pieces were completed; such parts must be separated from each other by straight lines parallel to the edges of the paper drawn with a ruler. You will lose points for otherwise. R Any sloppiness, untidiness, and any departure from proper format (as indicated in class) will lead to a score of 0.

E The 4digit number 2352 since 2 occupies the first and fourth positions, and 5 is strictly larger than 3 and the sum of the digits is 12, an even number. The 4digit number 2342 does not qualify as the sum of the digits is 11, not an even number. The number 2532 does not qualify as 3 is not strictly larger than 5. The number 2345 does not qualify as two distinct numbers occupy the first and fourth place.
