D, L, T, A, Q, D, L, S, Q, UAnswer by dabanfield(803)   (Show Source): You can put this solution on YOUR website!How many different 10 letter words (real or imaginary) can be formed from the following letters? D, L, T, A, Q, D, L, S, Q, U Since there are 10 letters so, assuming we cannot reuse a letter, the number of words is the number of ways we can arrange the 10 letters. There are 10 choices for the first letter. For each of these we have 9 choices for the second letter, and so on. So the total number of choices for all the positions we have 10*9*8*7*6*5*4*3*2*1 = 10!
