Given a special license plate tag consists of 6
characters for a small country.
the first 3 characters must be letters and the last 3
must be a single digit number _ characters can repeat-
the only restriction is that you 't have the first 3
characters be the same (eg- aaa. bbb, ccc, .
how many unique tags are possible?

First letter can be 1 out of 26

Second letter can be 1 out of 25

Third letter can be 1 out of 24

Each number can be 1 out of 10

Total combinations: 26 x 25 x 24 x 10 x 10 x 10 = 15,600,000

d. 17,550,000

Step-by-step explanation:

(26×26×26 - 26) × (10×10×10)

17,550,000

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
