huh pls vote branliest
Step-by-step explanation:
Using the Fundamental Counting Theorem, it is found that for each case, the total number of outcomes is:
a) 60,466,176.
b) 5,961,600.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

Item a:
No restrictions, hence for each of the five characters, there are 36 outcomes, hence
.
Then, the possible number of passwords is:

Item b:
The letters and the digits have to be alternated, hence:
- Starting with a letter,
.
- Starting with a digit,
.
Then, the possible number of passwords is:

If this means 3 divided by 125 the answer would be 0.024
Hope this helps. :)
Answer:
I think it is the last one.
Apply radical rule
= (10^1/2)3/4x
Apply exponent rule: (a^b)^c = a^bc
= 10^1/2 . 3/4x
Simplify: 1/2 . 3/4x: 3x/8
= 10^3x/8
(x + x² + 4x) 3
3(x) + 3(x²) + 3(4x)
3x + 3x² + 12x
