Question

Find the product by suitable rearrangement:
8 x 291 x 125

Answer 1

$\large{\text{(c) 8 x 291 x 125}}$



$\large{\text{= (8 x 125) x 291}}$



$\large{\text{= 1000 x 291}}$



$\large{\textbf{= 291000}}$

Answer 2

Given : The given multiplication is 8 × 291 × 125

To find : The answer to the given multiplication by suitable rearrangement.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the answer to the given multiplication)

Here, we will be using the rearrangement method instead of manual calculations. We will rearrange the numbers in such a way that, one of the multiplications will produce any multiple of 10. With that multiple of 10, the rest of the calculations will be extremely easier.

So,

= 8 × 291 × 125

= (8 × 125) × 291 [rearrangement done here]

= 1000 × 291

= 291000

(This will be considered as the final result.)

Hence, the answer is 291000
