The elements of the set are numbers 17, 26, 35, 44, 53, 62, 71, 80
As
0+8 = 8 but putting 0 in tens place makes it single digit number so will not consider it.
8+0 = 80, number is 80
1+7 =8, number is 17
7+1 =8, number is 71
2+6 = 8, number is 26
6+2 = 8, number is 62
3+ 5 = 8, number is 35
5+3 = 8, number is 53
4+ 4 =8, number is 44
Set in roaster form is
C= {17, 26, 35, 44, 53, 62, 71, 80}
