Final answer:

To add 7.14 x 10^10 and 3.15 x 10^10, sum the coefficients (7.14 + 3.15 equals 10.29) and keep the common exponent, resulting in the answer 10.29 x 10^10.

Step-by-step explanation:

The student's question involves the addition of two numbers that are written in scientific notation. This is a common operation in mathematics, specifically when dealing with very large or very small numbers. To add these numbers, we can simply add the coefficients (7.14 and 3.15) since the powers of 10 are the same (10^10 in both cases).

Here is the calculation step-by-step:

  1. Add the coefficients: 7.14 + 3.15 = 10.29.
  2. Since the exponent part (10^10) is the same for both numbers, we keep it the same in the result.
  3. Combine the sum of the coefficients with the exponent part to get the final answer: 10.29 x 10^10.

Therefore, the sum of 7.14 x 10^10 and 3.15 x 10^10 is 10.29 x 10^10.
