You should have done the infinite series for
(1+x)^(1/2)
so just do the same with the "x" replaced by "x^3". Upload what youve tried if you get stuck.
I'm sorry but how do we even expand the infinite series (1+x)^1/2

You should have covered it if youre expected to answer the question (is it a level?) but

If you have learned Maclaurin series (I suspect not, but alas, extra knowledge!), it's the same thing.
Plug in f(x) to be your binomial and you're good to go.
And this is especially nice for real powers of x, since power rule is easy.
