You can access individual elements of tuple by position with individual elements being named _1, _2 etc. :

val four = x._2._2._2._1

Or using pattern matching:

val (_,(_,(_,(four,_)))) = x

You can use pattern matching to decompose the expression:

scala> val (a,(b,(c,(d,e)))) = (1,(2,(3,(4,5))))
a: Int = 1
b: Int = 2
c: Int = 3
d: Int = 4
e: Int = 5

In case you are not interested in other values than 4:

scala> val (_, (_, (_, (x, _)))) = (1,(2,(3,(4,5))))
x: Int = 4
