Answers:

  • Estimate = 20,000 (underestimate)
  • Actual product = 21,285

Step-by-step explanation

4257 is close to 4000

5x4 = 20 which means 5x4000 = 20,000 is an estimate. It is an underestimate because 4000 is below 4257.

Here is one way we can find the actual product.

5x4257 = 5x(4000+200+50+7)

5x4257 = 5x4000+5x200+5x50+5x7

5x4257 = 20,000+1,000+250+35

5x4257 = 21,285 is the actual product

I used the distributive property on the second step.
