Step-by-step Solution

The notation \( \sum_{480}^{9} \) appears to be an attempt to express a summation, but it is not correctly formatted. The summation symbol \( \sum \) typically requires an index variable and a range of values over which to sum. If you meant to sum a sequence of numbers from 480 down to 9, you would typically write it as: \[ \sum_{n=9}^{480} n \] This would sum all integers from 9 to 480. However, if you meant to sum from 480 down to 9, it would be: \[ \sum_{n=9}^{480} n = \sum_{n=480}^{9} n \] But since the upper limit is less than the lower limit, this summation would be considered to be zero or undefined in standard mathematical practice. If you clarify your intention, I can provide a more specific answer!
