Oh, what a lovely thought! You could stack 77 books in so many ways, each one creating a unique and beautiful arrangement. Just imagine the different heights and patterns you could create - it's like painting a masterpiece with books. Remember, there's no right or wrong way to stack them, just let your creativity flow and enjoy the process.
To calculate the number of ways you can stack 77 books in a pile, you would use the factorial function. The factorial of a number is the product of all positive integers up to that number. In this case, the number of ways to stack 77 books would be 77 factorial (77!), which is an extremely large number - approximately 1.45183092 x 10^113. This means there are over 1.4 x 10^113 possible ways to stack 77 books in a pile.
5.This question is the same as asking how many factors does 18 have.18 has the following factors:1, 18, 2, 9, 3 & 6.Therefore you could pile the books 6 different ways.However, as the question says equal piles (plural) then I think we should probably discount 1 pile of 18 books, so the answer is 5.
240. 120 ways with the books stacked verticly, and 120 ways with the books stacked horizontaly, or one on top of the other.

10!/5!x5! 3,628,800/14,400 252. There are 252 ways.
Use the factors of the number. Factors of 10 are... 1,2,5 & 10. Therefore they will stack either in 1 row of 10 books or 2 rows of 5.
You can get a picnic basket and stack them up in there. Another trick is to stack them on a bookshelf if you have one. Simply place them between two hard books to keep them upright.
A deck can be divided into 3 piles with different numbers in each pile in 225 ways. This answer does not consider which cards are in which pile - only the number of cards in each pile.A deck can be divided into 3 piles with different numbers in each pile in 225 ways.

Two books are compulsory, so the student really wants to know how many ways he can pick 3 out of 7. That is 35.
