Homework Statement
there are 7 different french books and 7 different Spanish books, how many ways are there to arrange them on a shelf
a. books of the same language must be group together, French on left and Spanish on Right?
b. French and Spanish books must alternate in the grouping, beginning with a French book?
I tried doing 7!x7! for both of them but i don't think i am right?
