Question

(4x y)(5x^2yz) please I need it

Answer 1

Answer:

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

Step-by-step 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.

                                        $\begin{aligned}\\\small (4xy)(5x^2yz) &\equiv \small (4\times5)\times (x \times x^2) \times (y\times y) \times (z)\\\\&\equiv 20 \times x^3 \times y^2 \times z\\\\&\equiv 20x^3 y^2 z\end{aligned}$
