When we multiply an integer by a factor of 10, we add the zero to the end of the integer.
5(1 0)= 5 0
In this case, we are multiplying by 1000 which can be rewritten as three factors of 10. Therefore, to calculate the product we have to add three zeroes to the end of 180^(∘).
180^(∘)(1 000)= 180 000^(∘)
