# What's your password?

Level pendingAaron wants to create a Facebook account and change the password every day because he is afraid that someone might know his password

His password consists of 8 characters and he will only use the characters A to Z

Once he has changed his password he will not use the password he had used before

But he also wants to know how many password combinations does he have

The amount of the combinations of his passwords can be simplified as \(x\times10^y\) while \(x\) is a one digit number with many decimal places

Round off \(x\) to the nearest ones

What is \(x+y\)?
