What is (x+4)^4 expanded
(x+4)4=[(x+4)2]2|(x+4)2=x2+8x+16=(x2+8x+16)2=[x2+(8x+16)]2=(x2)2+2⋅x2⋅(8x+16)+(8x+16)2|(8x+16)2=(8x)2+2⋅8x⋅16+162=(x2)2+2⋅x2⋅(8x+16)+(8x)2+2⋅8x⋅16+162=x4+2⋅x2⋅8x+2⋅x2⋅16+64x2+256x+256=x4+16x3+32x2+64x2+256x+256=x4+16 x3+94x2+256x+256
(x+4)^4 is the same as (x+4)(x+4)(x+4)(x+4)
which can be further simplified to 4x+256

I just went to WolframAlpha :
