To express \( 8.64 \times 10^4 \) seconds in standard form, you need to calculate the value.
Calculating \( 8.64 \times 10^4 \):
\[
8.64 \times 10^4 = 8.64 \times 100,000 = 86,400
\]
So, \( 8.64 \times 10^4 \) seconds is equivalent to 86,400 seconds.
Therefore, the correct answer is:
**C. 86,400 seconds**
Calculating \( 8.64 \times 10^4 \):
