A license plate in a certain state consists of three digits, not necessarily distinct, and three letters, also not necessarily distinct. these six characters may appear in any order, except that the three letters must appear next to each other. how many distinct plates?

he three letters can form  26 * 26 * 26 combos = 17576

  they have four positions in the six string plate they can be in

     17576 x 4

   then the remaining 3 numbers can form 1000 combos

      17576 * 4 * 1000 = ________ combos
