Answer:
Two strategies that can be used to find the product of 1,587 x 1,000 are:
Putting 3 zeros on the end of 1,587: This strategy involves multiplying 1,587 by 1,000, which means adding three zeros to the end of 1,587. So, the product of 1,587 x 1,000 is 1,587,000.
Multiplying (1 + 5 + 8 + 7) x 1,000: This strategy involves finding the sum of the digits in 1,587, which is (1 + 5 + 8 + 7) = 21, and then multiplying this sum by 1,000. So, the product of 1,587 x 1,000 is 21,000.
Therefore, the options that represent these strategies are:
Putting 4 zeros on the end of 1,587
Multiplying (1 + 5 + 8 + 7) x 1,000
