Please help me understand how to go about this problem

Answer 1

to understand this question, you think 5 positions - - - - - , the first three you need fill numbers, and last two fill letters, for number you have 10 digits to choose from, for letter you have 26 to choose from , so the total choice is 10 *10 *10 *26 *26 =676000
