455 = (5)(91) = (5)(7)(13)

You can't simplify the radical.

You can write the whole thing as

$\dfrac 1 3 \left(-1 + \dfrac{\sqrt{455}}{12}\right)$

What are we going to consider "simplified" or "more simplified," if I were to force the question?

Adding up every little symbol, number, fraction bar, etc. in the offered expression, I counted 15 of them.
And there are two fractions involved with a product relying on parentheses.

I offer this one below. It consists of 11 components, as compared, respectively, to the other offered one.
And there is the one fraction and no parentheses or product involved.

$\displaystyle \dfrac{-12 \ + \ \sqrt{455}}{36}$
