Answer: 520

Step-by-step explanation:

Total choices for letters = upper case letters (26) + lower case letters (26).

= 26+26 = 52

Choices for digits = 10

By Fundamental counting principle,

The different five character passwords can be created = (Choices for letters) x (Choices for digits)

= 52 x  10

= 520

Hence, the number of different five character passwords can be created = 520
