Final answer:

To estimate the product of 726 × 5, round each number to the nearest ten and multiply. The exact product is found by multiplying 726 by 5.

Step-by-step explanation:

To estimate the product of 726 × 5, we can round each number to the nearest ten. So, 726 becomes 730 and 5 becomes 10. Then, we multiply 730 by 10 to get an estimation of the product which is 7300. To find the exact product, we multiply 726 by 5 which equals 3630.

Therefore, the correct answer is option b. 3600 (estimation); 3630 (exact).
