$7.348 \cdot {10}^{7}$

#### Explanation:

The key realization is that when we write numbers in scientific notation, we want one digit before the decimal point.

In our case, we must loop it $7$ times to the left. The number of times we loop it is our exponent, and looping left makes it positive. Thus, we have

$7.348 \cdot {10}^{7}$

Hope this helps!
