Show your work and leave your answer in exponential or factorial form.

With lower case numbers and numerals from 0-9 there are about 4,738,381,338,321,616,896 possible passwords.

Add up the number of possible numbers and letters.

There are 26 letters in the alphabet, 0-9 would mean 10 digits. Which is 36.

The length of the password she wants is 12.

36 to the power of 12 = 4738381338321620000

4738381338321620000
