1991\times 1005=20009551991×1005=2000955

Step-by-step explanation:

Given : Expression 1991\times 10051991×1005

To find : The product using suitable properties?

Solution :

Step 1 - Write the expression,

=1991\times 1005=1991×1005

Step 2 - Re-write 1005 as 1000+5

=1991\times(1000+5)=1991×(1000+5)

Step 3 - Apply distributive property, a(b+c)=ab+aca(b+c)=ab+ac

=1991\times 1000+1991\times 5=1991×1000+1991×5

=1991000+9955=1991000+9955

=2000955=2000955

Therefore, 1991\times 1005=20009551991×1005=2000955
