Someone doing university maths will for certain know a simple non-rational binomial expansion. They're doomed if they don't lol.

You should get a sum consisting of powers of x. Separate this infinite sum into two infinite sums; one consisting of terms with even powers only, and the other consisting of odd powers only. These two infinite sums are your two functions, one of which is even and another of which is odd.
ill ask you later about these question but can you walk me through the exercise 5 and 6 please

5) would be splitting the domain into intervals where you can remove the absolute values from the function in each interval, so, eg
|x| = -x when x<0
x when x>=0
For 4), Id do post 5. Just add to get the even and difference to get the odd.
