Question: Please help with math permutations problem?

1. In how many different ways can 6 knights be seated in 6 chairs around a round table?

Answer: 1. Since you specified a round table, I will assume it does not matter if you shift everyone around keeping them in the same order. Put 1 person in any seat. Then you can choose among 5 people to sit to his right, 4 people to sit to the right of that person, etc. So you have 5*4*3*2*1 or 120 ways.

2. Count the 2 people who must stand next to each other as 1 person. so you have 8*7*6*5*4*3*2 = 40320 ways. Or you can switch the order of those 2 people, giving you another 40320 ways, for a total of 80640.

3. The best hitter is fifth, so you can rearrange the other 8 players in 8*7*6*5*4*3*2*1 = 40320 ways.

Question: Math help, logarithm generator?

For a homework problem, I’m supposed to make up a bunch of log equations.

Answer: If they all have to be based on the definition of log like your example then you can make up heaps yourself pretty easily.

Just start with the b^a = x form then write it in log form

For example:

2^6 = 64
log(2) 64 = 6

5^3 = 125
log(5) 125 = 3

Just keep doing this sort of thing until you’ve got enough
