Answer:

No, 8000 is not a good estimate for the sum of 3816 + 487

We do the sum,


3816 + 487 = 4283\\

Now, since the correct answer is 4283, 8000 is a bad estimate of the sum.

Now, it is a bad estimate because it is very far from the correct answer, it is about 2 times away from the answer, for a good estimate, the estimate has to be close to the true value, in our case, a good estimate would be 4000
