Answer:

The solution is
x = -1

Explanation:

We have the following equation:


\sqrt[3]{5x-3} + 8 = 6

We place everything with the root on one side, everything without on the other site of the equality. So:


\sqrt[3]{5x-3} = -2

Elevating both sides to 3, we can isolate x


\sqrt[3]{5x-3}^(3) = (-2)^(3)


5x-3 = -8


5x = -5


x = -1

Checking


\sqrt[3]{5(-1) - 3)} + 8 = \sqrt[3]{-8} + 8 = -2 + 8 = 6
