30 pts + brainliest using the letters in the word innovative, find the number of permutations that can be formed using 4 letters at a time. show your work or explain how you got your answer.

5040

Step-by-step explanation:

npr = n! / (n - r)!

numbers of letters given = 10

permutation that can be formed using 4 letters at a time= 10 P ₄

=10! / (10 - 4)! = 10! / 6!

= 10 ×9 ×8×7 ×6! /6! ( the 6! will cancel out)

= 10×9 ×8×7=5040

Therefore, the number of permutations are 5040

Number of permutations = 5040

Step-by-step explanation:

We are given the word 'INNOVATIVE', that has total 10 letters.

Now, we are asked to form words using exactly 4 letters at a time i.e. out of 10 letters we are using 4.

Therefore, the number of permutations that can be formed using 4 letters are = P(10,4)

i.e.

=

=

=

= 10*9*8*7

= 5040

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
