Two forms of the decomposition for the coefficients of the masless perturbative QCD expression for the renormalization-group invariant Adler function are considered. The ansalysed decompositions are: the expansion in powers of number of quarks flavous N_f and the {beta}-expansion procedure in monoms , composed from the coefficients of the RG beta-function. The quest of relation of these two representations and renormalon language is considerd. Consequences of CBK relation are discussed
