Question

 Thu gọn đơn thức sau:

\(\left(-3x^2y^2\right)^2.\left(-2xy^3\right)^3\)

Answer 1

\(=\left(9x^4y^4\right).\left(-8x^3y^6\right)\)

\(=\left(-8.9\right).\left(x^4.y^4.x^3.y^6\right)\)

\(=-72x^7y^{10}\)

Answer 2

\(\left(-3x^2y^2\right)^2.\left(-2xy^3\right)^3\)

\(9x^4.y^4.\left(-8\right).x^3.y^9\)

\(-72.x^7.y^{13}\)
