The first is the Barrow entropy, which imposes a fractal structure on the black hole horizon area. While the second is the well-known <math><mi>f</mi><mo>(</mo><mi>R</mi><mo>)</mo></math> gravity, which comes from a generalization of the Einstein-Hilbert action. Using the ideas of gravity-thermodynamics conjecture, these two models are combined. Then the modified Friedmann equation is obtained. Choosing a particular <math><mi>f</mi><mo>(</mo><mi>R</mi><mo>)</mo></math> model, an application is investigated. The state parameter and the density parameters for matter and dark energy are calculated. With these results, the dynamic evolution of the universe is discussed."
