Question 1185123: Four different mathematics books, six different physics books, and two different
chemistry books are to be arranged on a shelf. How many different arrangements
are possible if the books in each subject must all stand together? Answer by Edwin McCravy(20054) (Show Source): You can put this solution on YOUR website!
3!=6 ways to arrange the 3 subjects.
4!=24 ways to arrange the 4 math books.
6!=720 ways to arrange the 6 physics books.
2!=2 ways to arrange the 2 chemistry.
That's (6)(24)(720)(2) = 207360 ways.
