**5. Conclusions**

In this research, the MHD flow of micropolar nanofluid over an exponentially shrinking surface was considered with the effect of the porous and velocity slip. Exponential similarity variables were used to convert the partial differential equations into quasi-ordinary differential equations. The resultant equations were converted from BVPs to IVPs using a shooting method, after which the IVPs were solved by an RK-4th order method. After the findings of multiple solutions of nanofluid flow, a stability analysis was performed in order to indicate the stable solution by using the BVP4C solver in MATLAB software. The main summary findings of our research are as follow:
