Answer:

Step-by-step explanation:
According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:

Where
represents the amount owed, and
represents weeks.
So, in the 4 week, that is,
he owed:

As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is

We have the following expression:
17 ^ (3/5)
We rewrite the expression.
We have then:
a ^ root (17 ^ b)
Where, for this case:
a = 5
b = 3
Substituting:
5 ^ root (17 ^ 3)
Answer:
the value of B is:
b = 3
1/4 + 1/3 + 1/6 + 1/8 + 1/8
Must have same denominators
6/24 + 8/24 + 4/24 + 3/24(2)
Answer: 1
The problem is a irrational number
