In the group {1, 2, .........16} under the operation of multiplication...
Here C1 = {1, 2, -----16} is group under the operation of multiplication moduo 17
So 34 = 81 = 13 (mod 17)
38 = 16(mod 17)
312 = 4(mod 17)
316 = 1 (mod 17)
⇒ order of the element 3 is 16
∴ 0(3) = 16
So 34 = 81 = 13 (mod 17)
38 = 16(mod 17)
312 = 4(mod 17)
316 = 1 (mod 17)
⇒ order of the element 3 is 16
∴ 0(3) = 16

Answer:
To find the order of an element in a group under a certain operation, we need to determine the smallest positive integer 'n' such that the element raised to the power of 'n' gives the identity element of the group. In this case, the identity element is 1.
Step 1: Multiplication Table
First, let's create a multiplication table for the group {1, 2, ..., 16} under the operation of multiplication modulo 17.
