How do you get to 147-02 34th Ave Flushing NY from Brooklyn NY?

It is impossible to provide directions without knowing 1) where in Brooklyn you're coming from, and 2) what method of transportation you plan to use (bus, subway, car).

Brooklyn is almost 100 square miles of dense urban landscape, criss-crossed by 14 different subway lines, a few dozen bus routes, and hundreds upon hundreds of streets and avenues. The directions will be completely different, depending on where in Brooklyn you're coming from, not to mention whether you're traveling by bus, subway or car.

Please ask your question again, this time including 1) an exact address or cross street in Brooklyn (or at the very least, a neighborhood), and 2) a method of transportation.
