Help.. Simple maths question

(A+A^b)^b

=A(1+A^(b-1))^b

That could not be further simplified.

I do not think you can do anything with that.....it is as simplified as you can make it.

Ummmm. I thought of binomial theorem.

$(A+A^b)^b\\ = A^b+\displaystyle C^{b}_{1}A^{2b-1}+C^{b}_{2}A^{3b-2}+C^{b}_{3}A^{4b-3}.......$
