To convert hours to days, we use the conversion factor that there are 24 hours in a day.

Given:
\( 7.8 \times 10^5 \) hours

We can convert this to days as follows:

\[
\text{Days} = \frac{7.8 \times 10^5 \text{ hours}}{24 \text{ hours/day}} = \frac{7.8 \times 10^5}{24}
\]

Calculating this:

\[
\frac{7.8}{24} = 0.325
\]

Now we can multiply \( 0.325 \) by \( 10^5 \):

\[
0.325 \times 10^5 = 3.25 \times 10^4
\]

Thus, \( 7.8 \times 10^5 \) hours is equal to \( 3.250 \times 10^4 \) days.

The correct response is:
**3.250×10^4 days**.
