Final answer:
To estimate the product (5.3 x 10^7) * (4.83 x 10^7), multiply the numbers without the powers of 10, then multiply the powers of 10 separately. The estimated product is 25.599 x 10^14.
Step-by-step explanation:
To estimate the product (5.3 x 10^7) * (4.83 x 10^7), we can first multiply the numbers without considering the powers of 10. 5.3 * 4.83 = 25.599.
Next, we multiply the powers of 10. 10^7 * 10^7 = 10^(7+7) = 10^14.
Therefore, the estimated product is 25.599 x 10^14.
