I found it thank you.

A. If I am planning to stay with a friend in another city 1. Moscow 2. Another city, but I also give details concerning the second destination and exact time of stay in the second city?

B. Must I show how long I will stay at the hotel in Moscow time of stay at another city and then return to the same hotel in Moscow before my departure?

Thank you
Lou

@Lou You only have to specify the cities you will visit in Russia, not the period you will be in each city. In any case, once you have obtained the visa you can move freely around Russia, even if you have not indicated all the cities on the form.
