You have to multiply
[tex](-2x^3y^2z)(5x^6yz)[/tex]
To solve this multiplication you can decompose the terms and multiply each like term separately.
So that
[tex]\begin{gathered} (-2)\cdot5=-10 \\ x^3\cdot x^6=x^9 \\ y^2\cdot y=y^3 \\ z\cdot z=z^2 \end{gathered}[/tex]
Once you solved each multiplication you can multiply all terms together
[tex](-10)(x^9)(y^3)(z^2)=-10x^9y^3z^2[/tex]
The correct answer is D.
