Can a excel formula be made for this equation?

I may as well be reading Chinese as my math doesn’t yet extend this far. Please excuse me I am just an aspirant practitioner. Can an excel formula be made to solve given values/variables for this equation?

Thanks in advance.

Hi xeven
Here is an idea: Try to solve the equation using Wolfram Alfa
