This is the problem: (2^m+1)^2 by the special product rules it equals 4^(mm)+4^m+1 but if I plug in 2 as m then (2^2+1)^2=25 but 4^4+4^2+1 does not equal 25 could someone please explain why this will not check

Using the ordinary product rule: $\displaystyle (2^m + 1)^2 = 2^{2m} + 2^{m+1} + 1 = 4^m + 2^{m+1} + 1$.
