License plates are made using 3 letters followed by 2 digits. How many plates can be made if repetition of letters and digits is allowed?

Number on license plates are of the form LLLDD, where L represents a letter and D represents a digit.
As L can be anything from A to Z, there are 26 combinations for that and as repetition is allowed,
for second and third letters, we again have 26 combinations available and thus ${\displaystyle 26\times 26\times 26=17576}$ combinations for letters.
But digits are from 0 to 9 i.e. 10 combinations for each place and tolal ${\displaystyle 10\times 10=100}$ combinations.
Hence for LLLDD, we have ${\displaystyle 1,757,600}$ combinations available for license plates.
