The correct answer is b- 8P4.
This is because the word "equation" has 8 letters, and you want to arrange them in a specific order. The formula for the number of arrangements is the permutation formula, which is nPr = n! / (n - r)!, where n is the total number of objects and r is the number of objects you want to arrange.
In this case, you want to arrange all 8 letters, so n = 8 and r = 8. Therefore, the number of ways to arrange the letters in "equation" is 8P8, which simplifies to 8! / (8 - 8)! = 8!.
Alternatively, you can choose to arrange only 4 letters out of the 8, which gives you 8P4. This formula is equivalent to 8! / (8 - 4)! = 8! / 4!, which also gives you the total number of arrangements of 8 objects taken 4 at a time.
which expression would you use to figure out the number of ways you can arrange the letters in the word equation?
a- 8!
b- 8P4
c- 4P8
d- 4!
