3649x7 = use distributive property to solve

25543

Step-by-step explanation:

The given expression to be solved is 3649*7

This can be written as,

7 * (3649)

We now write the number in the parenthesis in expanded form.

This implies,

7 * (3649) = 7 (3000+600+40+9)

we now expand the bracket to get

= (7*3000) + (7*600) + (7+40) + (7*9)

By simplification, we obtain

=21000+4200+280+63

=25543

Hence 3649*7=25543
