Question 4(d)

Find the product using suitable properties:

$1005\times 168$

Answer 1

$1005\times 168$

1005 can be split as (1000 + 5) as calculations with 1000 (or any power of 10) makes it easier and faster.

$=(1000+5)\times 168$

Now, we can use the distributive property,

a×(b+c)=(a×b)+(a×c)

and take 168 common

= $(1000\times 168)+(5\times 168)$

= $168000+840$

= $168840$
