Question

find value of n if,p(n,5)=42p(n,3)​

Answer 1

Hello, here's ur answer

Answer:

n=(-3),10

Step-by-step explanation:

nP5 = 42 * nP3

(n!) / {(n - 5)!} = 42 * (n!) / {(n - 3)!}

{(n - 3)!} / {(n - 5)!} = 42

(n - 3) * (n - 4) = 42

(n^2) - 7n + 12 = 42

(n^2) - 7n - 30 = 0

(n - 10) * (n + 3) = 0

n = (-3), 10
