Best answer

since A1  has dimension  m*n
               A2  has dimension  p*q

               A3  has dimension  q*r

          A4  has dimension  r*s

      A5 has dimension  m*n

(A1 A2 A3 A4 A5)m*s     so   it is equal to = 
 (   (   (  ( A1*A2 )*A3 ) *A4 )*A5  )

so here we found that we need 4 pair of parenthesis for full pair of parenthesization.
