How much does it cost to take a taxi from Longquan to Luodai Ancient Town?

Taxis are priced by the meter now, and you won't be charged more. Longquan goes to Luodai, probably 30 yuan.

If you want to go to the panda base, you can simply take a taxi, which is about 100- 150. It will be more troublesome if you take the bus. You have to take a taxi to Longquan bus terminal, where there are many buses to Chengdu Wuguiqiao bus station, and then there are buses to Xinnanmen tourist bus station, where there is a shuttle bus to Panda Base.
