Find the product by suitable arrangement:

125×40×8×25


Open in App
Solution

We can arrange the calculation in such a way that it becomes easy and quick to find the answer.

125×40×8×25

We club the product into two parts. We find the product of 125 and 8 as it gives 1000 and 40 and 25 as that gives 1000 too.

= (125×8)×(40×25)

So the over product gets simplified as:
= 1000×1000
= 1000000
