The estimate of the product is reasonable and the values are Estimate: 1,305 × 81 ≈ 104000 and Actual 1,305 × 81 = 105706

How to estimate and then compute the product check that your answer is reasonable?

The product expression is given as

1,305 × 81

As an estimate, we have

1305 = 1300

81 = 80

So, we have:

1,305 × 81 ≈ 1300 * 80

Evaluate the product

1,305 × 81 ≈ 104000

For the actual product, we have

1,305 × 81 = 105706

The estimate and the actual product both approximate to 100000

Hence, the estimate of the product is reasonable and the values are Estimate: 1,305 × 81 ≈ 104000 and Actual 1,305 × 81 = 105706
