PLEASEEEE PLEASEEEEEEEEE HELPPPPPPPPPP<br> how do i solve this equation?

Stells [14]

Answer:

360

Step-by-step explanation:

using the definition

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

where n! = n(n - 1)(n - 2)..... × 3 × 2 × 1

then

6 $P_{4}$

= $\frac{6!}{(6-4)!}$

= $\frac{6!}{2!}$

= $\frac{6(5)(4)(3(2)(1)}{2(1)}$ ← cancel 2(1) on numerator / denominator

= 6 × 5 × 4 × 3

= 360
