Question

Find the product by suitable rearrangement

$618\times 16\times 625$

Answer 1

Step $1:$ Firstly multiply $16\times 625$

$$\begin{gathered} \Rightarrow 618\times (625\times 16) \\ \Rightarrow 618\times 10000 \end{gathered}$$

Step $2:$ Then multiply $618\times 10000$

$$\begin{gathered} \Rightarrow 618\times 10000 \\ \Rightarrow 6180000 \end{gathered}$$

Hence, the answer is $6180000$.
