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

We have 26 letters in the alphabet
We have 10 digits [0-9]

The problem asks for the following license plate scenario of Letters (L) and Digits (D)
LLLDDD

The number of plates we can make using L = 26 and D = 10 using the fundamental rule of counting is:
Number of License Plates = 26 * 26 * 26 * 10 * 10 * 10
Number of License Plates = 17,576,000
