The main approach is to express all the numbers involved in the LHS (Left Hand Side) of the equation in terms of {3} first so that it is easier to do addition, since you have one that is already expressed in terms of {3}. Once the LHS is simplified it should be easy for you already. Hope this is clear enough. Cheers and all the best! :)

Sorry forgot to tell you that {3} means square root of 3.
I think you've made a mistake there. 81 is not 3²
Thank you!
Ah yes apologies I overlooked that. 81 is 3 to the power of 4, not 2. I was rushing the solution just now. Thanks for pointing it out!
