Answer:

x = 21

Explanation:

(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.

You can bring the cube root to the other side of the equation.

1. I chose to bring it to the other side of the equation, making it a cube.

(3x+1) ^1/3 = 4

(3x+1) = 4^3

(3x+1) = 4 * 4 * 4

(3x+1) - 1 = 64 - 1

3x/3 = 63/3

x = 21
