Question

Find the product by a suitable rearrangement:
$4\times 166\times 25$

Answer 1

$4\times 166\times 25$ can be written as:
$=166\times \left(4\times 25\right)$ (By using associative property)
$$\begin{gathered} =166\times 100 \\ =16600 \end{gathered}$$ (By removing bracket)
Hence the value $4\times 166\times 25=16600$
