the license plate has 4 letters followed by 2 numbers.

there are 26 possible letters for each letter position.

there are 10 possible numbers for each number position.

the total number of license plates will be equal to 26^4 * 10^2 = 45,697,600.

if you assume small letters and big letters can be used, then the number of possible license places will be 52^4 * 10^2 = 731,161,600.

nomall, only capital letters are used, so your answer should be 45,697,600 license plates can be issued.
