Answer:
25543
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
