Answer:

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
