Question

Calcule A3,2+C5,2-P3

Answer 1

An,p = n! / (n-p)!

Cn,p = n! / p!(n-p)!

Pn = n!

____________________________________

A3,2 + C5,2 - P3

3! / (3-2)! + 5!/2!(5-2)! - 3!

3! / 1! + 5! / 2!3! - 3!

6 / 1 + 120 / 2*6 - 6

6 + 10 - 6

10

Answer 2

Resposta:

A₃,₂₂ + C₅,₂ - P₃ = 10

Explicação passo-a-passo:

A₃,₂₂ + C₅,₂ - P₃ = $\frac{3!}{1!} + \frac{5!}{2! 5!} - 3! = 10$
