00:01 Hello friends, in this question we need to find the chromatic index of each graph.
00:05 The first one we see that the chromatic index of a path graph, p .n is always 2.
00:29 Therefore, the chromatic index of p12 is equal to 2.
00:42 Next one, for cn we have n as greater than or equal to 3.
00:55 Therefore, the chromatic index of cn is equal to 2 if n is even.
01:08 It is 3 if n is odd.
01:16 Therefore, the chromatic index of c6 is equal to 2 as 6 is even, and c5 is equal to 3 as 5 is odd...
