Answer:
The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
1. Remove the parenthesis using the next rules:

<h2>Then, the solution is 8</h2>
Nine days. You can divide 108 by 36, to get how many times she has to read 36 pages, which is 3. Then you multiply that by 3, because she uses 3days for every 36 pages. 3x3=9
