In how many different ways can the letters of the word "COMPUTER" be arranged?
The word "COMPUTER" has 8 letters. To find the number of ways the letters can be arranged, we use the formula for permutations of a set with repetition.
The formula for permutations of a set with repetition is given by:
n! / (n1! * n2! * ... * nk!)
Where n is the total number of items and n1, n2, ..., nk are the frequencies of each item.
In this case, there are 8 letters in total.
The letter 'C' appears once, 'O' appears once, 'M' appears once, 'P' appears once, 'U' appears once, 'T' appears once, 'E' appears once, and 'R' appears once.
So the formula becomes:
8! / (1! * 1! * 1! * 1! * 1! * 1! * 1! * 1!)
Simplifying this expression, we get:
8! / 1
Since any number divided by 1 is equal to the number itself, we can simplify further:
8!
Calculating this expression, we find:
8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40,320
Therefore, there are 40,320 different ways the letters of the word "COMPUTER" can be arranged.
