Question

Verify and name of the property used.

$5\times \left[\left(-20\right)\times 7\right]$

Answer 1

Verify the expression:

Using associative property we get,

$$\begin{gathered} 5\times \left[\left(-20\right)\times 7\right]=5\times \left(-20\right)\times 7 \\ =-100\times 7 \\ =-700 \end{gathered}$$

Hence, the property used is associative property .
