#### Work Step by Step

RECALL:
In the scientific notation $a \times 10^{n}$, $1 \le a \lt 10$ and $n$ is an integer.
Move the decimal point 13 places to the left to obtain $-4.1$.
To retain the value of the given number, multiply $10^{13}$ to $-4.1$.
Thus, the scientific notation of the given number is:
$=-4.1 \times 10^{13}$
