Answer:

25!=15511210043330985984000000

Step-by-step explanation:

We are asked to find the number of ways 25 students line up for lunch.

Since there are 25 students, so the students for the 1st place can be chosen in 25 ways.

As 1 student is already chosen for 1st place and there are 24 students left, so the students for the 2nd place can be chosen in 24 ways.  

Since 2 students are already chosen and there are 23 students left, so the students for the 3rd place can be chosen in 23 ways.

We will continue this process till we fill all the 25 places.

\text{The number of ways to line up for lunch}=25*24*23*22*21*20*19*.......*1

We can represent 25*24*23*22*21*20*19*.......*1 as 25!, therefore, 25 students can be line up for lunch in 25!=15511210043330985984000000 different ways.
