A sample license plate would be, say,

R U 7 2 4

There are 26-5 or 21 consonants (non-vowels) we can choose to put
where the R is.

There are 26 letters which we can choose to put where the U is.

There are 9 digits we can choose to put where the 7 is.

There are 10 digits we can choose to put where the 2 is.

There are 10 digits we can choose to put where the 4 is.

Multiply them all together:

21×26×9×10×10 = 491,400
