Question

calcule a- 8!/6!= b-4!/6!= c-7!/2! 5! d- 7!/3! 5!

Answer 1

a- 8!/6!=8*7*6!/6!=56
 
b-4!/6!=4!/(6*5*4!)=1/30
 
c-7!/(2! 5!)=7*6*5!/(2*5!)=21

d- 7!/(3! 5!)=7*6*5!/(2*3*5!)=7

Answer 2

Boa noite Rayla

a)  8!/6! = 8*7 = 56 

b)  4!/6! = 1/30 

c) 7!/2!5! = 7*6/2 = 21 

d) 7!/5!3! = 7*6/6  = 7
