Detailed deducing of formulas for longitudinal electric conductivity anddielectric permeability in the quantum degenerate collisional plasma withconstant collision frequency in Mermin' approach is given. The kineticSchr\"{o}dinger-Boltzmann equation in momentum space in relaxationapproximation is used. It is shown that when collision frequency of plasmaparticles tends to zero (plasma passes to collisionless one), the deducedformula for dielectric function passes to the known Lindhard' formula forcollisionless plasmas. It is shown that the deduced formula for dielectricpermeability coincides with known Mermin's formula. Graphic research of thereal and imaginary parts of dielectric function is made. Graphic comparison ofthe real and imaginary parts of dielectric function for quantum and classicalplasma also is made. The module of derivative dielectric function also has beeninvestigated graphically.
