Answer:


\hookrightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096

solving steps:


\rightarrow \sf (x + 4)^6


\bold{rewrite \ the \ following}


\rightarrow \sf (x + 4)^2 (x + 4)^2 (x + 4)^2


\bold {formula \ used : \sf (x+a)^2 = (x^2 + 2xa + a^2)}


\rightarrow \sf (x^2 + 8x+16) (x^2 + 8x+16) (x^2 + 8x+16)


\bold{simplify \ by \ removing \ parenthesis}


\rightarrow \sf (x^4 +8x^3 + 16x^2 + 8x^3 +64x^2 + 128x+16x^2+128x+256 ) (x^2 + 8x+16)


\bold{basic \ addition \ of \ integers }


\rightarrow \sf (x^4+16x^3+96x^2+256x+256) (x^2 + 8x+16)


\bold{remove \ parenthesis}


\rightarrow \sf (x^6 + 16x^5 + 96x^4 + 256x^3 + 256x^2 + 8x^6 + 128x^4 + 768x^3 + 2048x^2 + 2048 + 16x^4 + 256x^3 + 1536x^2 + 4096x + 4096)


\bold {final \ answer:}


\rightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096
