Explanation:

To find : Explain how finding
`4* 384` can help you find
`4* 5384` then find both products ?

Solution :

First we find the product of
`4* 384`

`4* 384=1536` .....(1)

Now, to find the product of
`4* 5384`

We can re-write the product as,

`4* 5384=4* (5000+384)`

Apply distributive property,
`a(b+c)=ab+ac`

`4* 5384=4* 5000+4* 384`

Using (1),

`4* 5384=20000+1536`

`4* 5384=21536`
