1)Resolva:
a)3.P5+7!+A3,2=
b)C4,3+C5,3-P3+2!=​

Answer 1

Resposta:

Explicação passo a passo:

a.

P5=5!=120

A3,2=3!/(3-2)!=3!/1!=6/1=6

3.P5+7!+A3,2=

3.120+5040+6=

360+5040+6=

5406

b.

C4,3=4!/3!(4-3)!=4.3!/3!1!=4/1=4

C5,3=5!/3!(5-3)!=5!/3!2!=5.4.3!/3!2!=5.4/2=20/2=10

P3=3!=6

C4,3+C5,3-P3+2!=

4+10-6+2=

14-6+2=

8+2=

10
