Please do Exercise 14.3.17 part A,C,E and please show step by step and explain

Example 14.3.16. At the beginning it may be helpful to draw a picture, as
in the previous example. However, once you gain experience, you should be
able to find the product of cycles directly. Consider the product or where
a = (AEDBF) and 7 = (ABDFE). Then we have:
• 1 takes A → B and o takes B →F; hence or takes A → F.
• takes F → E, and o takes E → D; hence or takes F + D.
• 1 takes D+ F, and o takes F + A; hence or takes D → A.
We have finished a cycle: (AFD). Let us check where the other letters
B,C, E go:
T takes B → D, and o takes D - B; hence oT takes B + B.
Neither 7 nor o affects C; hence or takes C -C.
I takes E → A, and o takes A → E; hence or takes E → E.
Since B, C, E are unaffected by or, we conclude that or = (AFD).
Exercise 14.3.17. Given that ð = (135), a = (347), and p = (567) are
permutations in S7, compute the following:
(a) ốo
(c) ốp
(e) op
(b) aổ
(d) på
(f) po
