A website password can consist of any combination of uppercase letters, lowercase letters, and digits from 0 to 9, and repetition is permitted. How many passwords of length five can be formed?

916132832

Step-by-step explanation:

There are 62 possible characters for each digit (uppercase=26, lowercase=26, 0-9=10)

26+26+10=62

You need to do 62 for each digit, so 62*62*62*62*62, or 62^5

Hope this helps :)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
