\(A=\frac{19}{5}xy^2.\left(x^3y\right).\left(-3x^{13}y^5\right)^0\)

\(A=\frac{19}{5}xy^2.\left(x^3y\right).1\)

\(A=\frac{19}{5}xy^2.\left(x^3y\right)\)

\(A=\frac{19}{5}x^4y^3\)

Vậy \(A=\frac{19}{5}x^4y^3\)

Answer 2

[๖²⁴ʱTú❄⁀ᶦᵈᵒᶫ]

\(A=\frac{19}{5}xy^2\left(x^3y\right)\left(-3x^{13}y^5\right)^0\)

\(=\frac{19}{5}xy^2\left(x^3y\right)\)

\(=\frac{19}{5}\left(xx^3\right)\left(y^2y\right)\)

\(=\frac{19}{5}x^4y^3\)
