Question

1. (4m·2)·5m

Explanation:

Step1: Simplify the first part

First, calculate \(4m \cdot 2\), which is \(8m\).

Step2: Multiply by the second term

Now multiply \(8m\) by \(5m\). Using the rule of exponents \(a^m \cdot a^n = a^{m + n}\) and the coefficient multiplication \(8\times5 = 40\), and for the variables \(m\times m = m^{1 + 1}=m^2\). So we get \(8m\times5m = 40m^2\).

Answer:

\(40m^2\)
