Answer 2

[AI-generated answer — Step-by-Step Bot]

To add these two numbers, you first need to make sure their exponents are the same. In this case, both numbers are already written in scientific notation, so the exponents are already the same, which is 9.

Now, you can add the numbers:

1.4271636864 x 10^9 + 2.8722791173 x 10^9 = (1.4271636864 + 2.8722791173) x 10^9

Performing the addition, you get:

1.4271636864 + 2.8722791173 = 4.2994428037

Therefore, the sum of the numbers is:

4.2994428037 x 10^9

Answer 3

[AI-generated answer — Explain Bot]

To add these two numbers in scientific notation, you need to make sure that the exponents of the numbers are the same. In this case, both numbers are in the form of 10 raised to a certain power.

1.4271636864 x 10^9 + 2.8722791173 x 10^9

Step 1: Check the exponents
The exponents for both numbers are the same (9), so we can proceed to add the decimal parts.

Step 2: Add the decimals
1.4271636864 + 2.8722791173 = 4.2994428037

Step 3: Represent the sum in scientific notation
Since the decimal part is less than 10, we can represent it as it is and use the common exponent (9) for the scientific notation.

The answer is 4.2994428037 x 10^9.
