Calculate the number of second in one week express the number in standard form

There are 60 seconds in 1 minute.

There are 60 minutes in 1 hour.

There are 24 hours in 1 day.

There are 7 days in 1 week.

Total seconds = (seconds/minute) $\times$ (minutes/hour) $\times$ (hours/day) $\times$ (days/week)
Total seconds = $60 \times 60 \times 24 \times 7$
Total seconds = $3600 \times 24 \times 7$
Total seconds = $86400 \times 7$
Total seconds = 604800

To express 604,800 in standard form, we move the decimal point to the left until there is only one non-zero digit before the decimal point.
$604800 = 6.048 \times 10^5$ (The decimal point was moved 5 places to the left).

The number of seconds in one week is $6.048 \times 10^5$.
