Question

A= -1/2 x^2y . ( -2xy^2z)^2 . 3 xz .

thu gọn đơn thức A

Louis Pasteur · Accepted Answer

$A=-\frac{1}{2}x^22y.\left(-2xy^2z\right)^2.3xz$

$a=-\frac{1}{2}x^22y.\left(-2\right)^2.x^2.\left(y^2\right)^2.\left(z\right)^2.3xz$

$A=-\frac{1}{2}x^2.2y.4.x^2.y^4.z^2.3xz$

$A=\left(-\frac{1}{2}.2.4\right).\left(x^2.x^2.x\right).\left(y.y^4\right).\left(z^2.z\right)$

$A=-4.x^5.y^5.z^3$

$A=-4x^5y^5z^3$

Câu trả lời:

$A=-\frac{1}{2}x^22y.\left(-2xy^2z\right)^2.3xz$

$a=-\frac{1}{2}x^22y.\left(-2\right)^2.x^2.\left(y^2\right)^2.\left(z\right)^2.3xz$

$A=-\frac{1}{2}x^2.2y.4.x^2.y^4.z^2.3xz$

$A=\left(-\frac{1}{2}.2.4\right).\left(x^2.x^2.x\right).\left(y.y^4\right).\left(z^2.z\right)$

$A=-4.x^5.y^5.z^3$

$A=-4x^5y^5z^3$
