Hi there! Hopefully this helps!

------------------------------------------------------------------------------------------------------------

The answer:
(7)/(9).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


\sqrt[]{2} ×
(8√(2) )/(3) ÷ 3 - 1

First, we express
√(2) ×
((8√(2))/(3)) ≈ 5.333333333 as a single fraction.


\frac{\sqrt{2 * 8√(2) } }{(3)/(3) } - 1 ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now we express
\frac{\sqrt{2 * 8√(2) } }{(3)/(3) } ≈ 1.777777778 as a single fraction.


\frac{\sqrt{2 * 8√(2) } }{3 * 3} - 1 ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Multiply
√(2) ≈ 1.414213562 and
√(2) ≈ 1.414213562 to get 2.


(2 * 8)/(3 * 3) - 1 ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Multiply 2 and 8 to get 16.


(16)/(3 * 3) - 1 ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Multiply 3 and 3 to get 9.


(16)/(9) - 1 ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Convert 1 to fraction
(9)/(9) = 1.


(16)/(9) - (9)/(9) ≈ 0.777777778

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Since
(16)/(9) ≈ 1.777777778 and
(9)/(9) = 1 have the same denominator, subtract them by subtracting their numerators.


(16 - 9)/(9)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then you get................


(7)/(9)
