The chain rule used in differentiation is it a must to have two functions divided by each other so that  i can use it what i mean is i can deffrentiate (x+3)/(x+5) this using the rule  can i use the same way in deffrentiating  (1)/(x+4)

I guess you meant the quotient rule.
Yes, i guess you can use it for the 2nd equation as well..but that isnt the best way. You can simply bring the (x + 4) up as (x+4)^-1 and solve it using the chain rule

yeah i don't their names :p anyway thanks :)
