The mathematical expression shown in the image is:

\[
(7.18 \times 10^{-7}) + (9.48 \times 10^{-9})
\]

Now, let's calculate the result:

1. Convert both terms to decimal form:
   - \(7.18 \times 10^{-7} = 0.000000718\)
   - \(9.48 \times 10^{-9} = 0.00000000948\)

2. Add them together:
   \[
   0.000000718 + 0.00000000948 = 0.00000072748
   \]

3. The result in scientific notation is:
   \[
   7.2748 \times 10^{-7}
   \]

So, the final answer is:

\[
7.2748 \times 10^{-7}
\]
