yo might be tricked to do 2(-7) but that's multiplcation

so expoments
(-6)^2=36

now we have
36/12-2(-7)
mulitipictioan or division whicever comes first
division
36/12=3
multiplcation 2(-7)=-14
now we have
3-(-14)
3+14
17

The expression P(4, 3) is equal to: -3! -4! - 1

nexus9112 [7]

Answer:

$P(4,3) = 4!$

Step-by-step explanation:

Given

P(4,3)

Required

Solve

Using permutation formula;

$P(n,r) = \frac{n!}{(n-r)!}$

This implies that

$P(4,3) = \frac{4!}{(4-3)!}$

$P(4,3) = \frac{4!}{(1)!}$

$P(4,3) = \frac{4!}{1!}$

$P(4,3) = \frac{4!}{1}$

$P(4,3) = 4!$
