    that's the right side, what about 3(x+1)^(1/5) + 5 - 5 = ?

    All you have to do is the following: Step 1: Simplify the equation step 2: Subtract both sides of the equation by whatever value you are using. Step 3: Multiply both sides. Step 4 : NOW YOU GET UR FINAL ANSWER. DON'T FORGET TO CHECK UR WORK :D

    \[(x+1)^{\frac{1}{5}} =2 \]Now the fifth roots of unity are \(z_k = e^{\frac{2\pi k}{5}i}\) where \(k = 0, 1, 2, \cdots, 4\). So the fifth roots of 2 should be \(z'_k = 2^{1/5} z_k \).
