4.4951 X 10^9 + 2.8725 X 10^9

Question

Explain in scientific notation.

Answer 1

To add these two numbers in scientific notation, we first need to ensure that the exponents are the same. In this case, both numbers have an exponent of 9.

Next, we can add the coefficients:

4.4951 + 2.8725 = 7.3676

Finally, we write the result in scientific notation:

7.3676 x 10^9
