If they share something, it can be factored.

I'm sure if you expand (ab)^4n, you won't get a^4n  b^4n

\[\large{\color{blue}{a^{4n}b^{4n} = (a^{2n})^2  (b^{2n})^2 = (a^{2n} + b^{2n} )(a^{2n}b^{2n})}}\]

a^2n  b^2n can be further factorised!

The identity used here is \(\large{\color{red}{a^2b^2=(a+b)(ab)}}\)

\[\large{(a^{2n}+b^{2n})(a^{2n}b^{2n}) = (a^{2n}+b^{2n})[(a^n)^2  (b^n)^2] \\= (a^{2n}+b^{2n}) (a^n + b^n)(a^nb^n)}\]

but a^(2n)+b^(2n) cant be furthur factorized?

Yes @tok1997 a^(2n)+b^(2n) can not be further factorised but a^(2n)b^(2n) can be.
