Answer: 26 x 36 x 36 x 36 x 36 x 36 x 36 x 36
You may also see it written as 26 x (36)^7
To understand this expression, you must first know that they are 26 letters and 10 digits (1 through 9 and zero).
Now, to find the total number of possibilities, you simply multiply all of the options for each position in the password.
First, we must have a letter, so there are 26 options. Then, for the remaining 7 places, there are 36 options (26 letters and 10 digits).
