Use the period and apparent visual magnitude of 2 cepheis log10P1 = 1.36, vị log10P2 = 1.62, v2 visual extinction is 0.15 magnitudes and compare your results with the measurement of 17.1 ± 1.8 Mpc obtained using many cepheis from M100. 26.3 and = 25.5 to calculate the distance to the galaxy M100. Use that the mean

Useful formula: 

m - M= 5 Log10 (d/10 pc)

you should have something like this:

d = (10)^ m-M+5/5  - (0.15)

note: that in the formula above, I have [ m-M+5/5 ] is raised to the power. It shows from the way I raised an arrow next to 10. Thank you so much.

Use the period and apparent visual magnitude of 2 cepheis log10P1 = 1.36, vị = 26.3 and log1, P2 = 1.62, v2 = 25.5 to calculate the distance to the galaxy M100. Use that the mean visual extinction is 0.15 magnitudes and compare your results with the measurement of 17.1 + 1.8 Mpc obtained using many cepheis from M100.
