Question

Express your answer in scientific notation.
8.8x10^7+3.1 x10^8

Answer 1

To add the numbers \( 8.8 \times 10^7 \) and \( 3.1 \times 10^8 \), we first need to express them with the same exponent.

We can convert \( 8.8 \times 10^7 \) to the same exponent as \( 3.1 \times 10^8 \):

\[
8.8 \times 10^7 = 0.88 \times 10^8
\]

Now we can add the two expressions:

\[
0.88 \times 10^8 + 3.1 \times 10^8 = (0.88 + 3.1) \times 10^8 = 3.98 \times 10^8
\]

Thus, the answer in scientific notation is:

\[
\boxed{3.98 \times 10^8}
\]
