To add the numbers in scientific notation:
Step 1: Arrange the given numbers to have the same exponent.
4.4951 × 10^9 + 2.8725 × 10^9
Step 2: Sum the coefficients.
4.4951 + 2.8725 = 7.3676
Step 3: Keep the same exponent.
The exponent remains as 10^9.
Step 4: Write the final answer in scientific notation.
7.3676 × 10^9
4.4951 X 10^9 + 2.8725 X 10^9
Step by step in scientific notation.
