A license plate is to have 3 digits followed by 2 uppercase letters. What is the number of different license plates possible if repetition of numbers and letters is not permitted?

Can we start with zero?
if so, then number of plates
=10x9x8x26x25 = 468000
If we can't start with a zero
= 9x9x8x26x25 = 421200
