Listing is for finite or "countable" sets -whatever that means to you.
49. list x-value(s) for which the equality holds
50. 0,1,2,3,4 since 5!=120
51. 0,1,2,3,4,5,6,7
52.a. P (10,3) order matters
b. P (6,3)
c. could be answer to a but I am not entirely sure.
Follow for solutions.
I believe the next one would be 13.2 because if you add 8.4 to -6.4 it gets 4.8 so you just do the same thing
Hello!
The most logical equation would be b)
