How do i execute expanding bracket problems?

Hi

I was wondering if i am able to solve bracket manipulation problems such as:

(a+b)(a+b) = a^2+2ba+b^2

and with additional powers

(3^n+4^n)^2

Thanks Jonathan

If you have the Symbolic Toolbox, you can do this:

syms a b
expand((a+b)*(a+b))
syms n
expand((3^n+4^n)^2)
