       \(4x^4+4x^3+5x^2+2x+1\)

\(=\left(2x^2\right)^2+2.2x^2.x+x^2+4x^2+2x+1\)

\(=\left(2x^2+x\right)^2+2\left(2x^2+x\right)+1\)

\(=\left(2x^2+x+1\right)^2\)

       \(x^4+6x^3+11x^2+6x+1\)

\(=\left(x^2\right)^2+2.x^2.3x+\left(3x\right)^2+2x^2+6x+1\)

\(=\left(x^2+3x\right)^2+2\left(x^2+3x\right)+1\)

\(=\left(x^2+3x+1\right)^2\)

Chúc bạn học tốt.

       \(81^7-27^9-9^{13}\)         

\(=\left(3^4\right)^7-\left(3^3\right)^9-\left(3^2\right)^{13}\)

\(=3^{28}-3^{27}-3^{26}\)

\(=3^{26}\left(3^2-3-1\right)\)

\(=3^{26}.5\)

\(=3^{22}.3^4.5=3^{22}.405⋮405\)

       \(12^{2n+1}+11^{n+2}\)

\(=144^n.12+11^n.121\)

\(=144^n.12-11^n.12+11^n.133\)

\(=\left(144^n-11^n\right).12+11^n.133\)

Ta có: \(a^n-b^n⋮a-b\Rightarrow144^n-11^n⋮133\)

Vậy \(12^{2n+1}+11^{n+2}⋮133\)
