In how many ways can I arrange 3 different math books and 6 different history books on my bookshelf, if I require there to be a math book on both ends?

Assuming all of the books are distinguisible

6 ways to have math on each end

   then there is 7 books left     7 P 7 = 5040  ways to arrange the 7 books

 

5040 x 6 = 30 240 ways  (I think) cheeky
