Answer 1

\[\huge \color{green}{-2x^8}\cdot\color{cornflowerblue}{3y^9}\cdot\color{orangered}{2x^4}\]Let's start by multiplying the green and orange terms first.
When you multiply terms with similar bases you ADD the exponents.\[\huge \color{green}{-2}\cdot\color{orangered}{2x^4}\color{green}{x^8} \qquad = \qquad \color{green}{-2}\cdot\color{orangered}{2}x^{4+8}\]

Answer 2

Which leaves us with this,
\[\huge \color{green}{-4x^{12}}\cdot\color{cornflowerblue}{3y^9}\]

Answer 3

Then just multiply the 3 and the 4 :O
Hmm maybe it would have been easier to move the constants out front, and multiply those first. I hope I didn't confuse you :3
