Can anyone explain how to do this physics problem?

Our galaxy, the Milky Way, contains approximately 4.0 times 10 to the 11th power stars with an average mass of 2.0 time 10 to the 30th power kg each. How far away is the Milky Way from our nearest neighbor, the Andromeda Galaxy, if Andromeda contains roughly the same number of stars and attracts the Milky Way with a gravitational force of 2.4 times 10 to the 30th power N?

Thanks so much for reading!!!
