Answer 1

(4xy)(5x^2yz) = 20x^3y^2z

Explanation:

• You need to expand the brackets by multiplying compatible terms together.
• The numerical ones together and algebraic ones of the same variable together as well.
• You may follow the following steps to understand the way it is done.

`\begin{aligned}\\\small (4xy)(5x^2yz) &\equiv \small (4*5)* (x * x^2) * (y* y) * (z)\\\\&\equiv 20 * x^3 * y^2 * z\\\\&\equiv 20x^3 y^2 z\end{aligned}`
