#### Work Step by Step

RECALL:
To write a number that is in scientific notation, which has the form $a \times 10^n$, in decimal notation, we:
(i) Move the decimal point $n$ places to the right if $n \gt 0$
(ii) Move the decimal point $|n|$ places to the left if $n\lt 0$
The given scientific notation has $n=6$.
Use rule (i) above to obtain:
$=-8,170,000$
