To write the number $7,300$ in scientific notation, we need to express it in the form:

$a \times 10^n$

where $a$ is a number between $1$ and $10$, and $n$ is an integer.

Steps:

1. Move the decimal point in $7,300$ to create a number between $1$ and $10$. Moving the decimal two places to the left gives us $7.3$.
2. Since we moved the decimal two places, we multiply $7.3$ by $10^3$.

Thus, $7,300$ in scientific notation is:

$7.3 \times 10^3$
