Hello!

I love your pfp :))

So, lets turn everything where the base is 2.

2^(1/3) is already in base 2.

4^(1/9) = (2^2)^(1/9) = 2^(2/9)

8^(1/27) = (2^3)^(1/27) = 2^(3/27) = 2^(1/9)

16^(1/81) = (2^4)^(1/81) = 2^(4/81)

Now that everything is in base 2, we can just add. :))

1/3+2/9+1/9+4/81 = 58/81

2^(58/81) = <81>sqrt(2^58)

I hope this helped. :))
