Work Step by Step
There are 10 different digits and 26 letters.
(1) A digit from 1 to 9 gives 9 different possibilities
(2) A letter: 26 possibilities
(3) A dot: one possibility
(4) A letter: 26 possibilities
(5) A four digit number not ending with 0: The first 3 digits can be one of 10 digits, the fourth can only be one of 9 digits (it can not be 0) This gives $10^3*9$ possibilities
Ovarall the number of different license plates is $9*26*1*26*10^3*9=54,756,000$
