\( \frac{4}{1 - \sqrt[3]{3}} + \sqrt[3]{9} \)
Note that 1 - 3 can be written as ( 1 - 3^(1/3)) ( 1 + 3^(1/3) + 3^(2/3))
Multiply num/den of the first fraction by the expression in re and we get
4 (1 + 3^(1/3) + 3^(2/3) )
_____________________ = -2 ( 1 + 3^(1/3) + 3^(2/3) ) = -2 - 2*3^(1/3) -2*3^(2/3)
1 - 3
And 9^(1/3) = 3^(2/3)
So we have
-2 -2*3^(1/3) - 2 *3^(2/3) + 3^(2/3) =
-2 - 2*3^(1/3) - 3^(2/3)
