Answer

x=18x = \frac{1}{8}

Step-by-step solution

3 steps
  1. Add 3 to both sides of the equation.

    8x13−3+3=1+38x^{\frac{1}{3}} - 3 + 3 = 1 + 3 8x13=48x^{\frac{1}{3}} = 4
  2. Divide both sides by 8.

    8x138=48\frac{8x^{\frac{1}{3}}}{8} = \frac{4}{8} x13=12x^{\frac{1}{3}} = \frac{1}{2}
  3. Cube both sides of the equation to solve for xx.

    (x13)3=(12)3(x^{\frac{1}{3}})^3 = \left(\frac{1}{2}\right)^3 x=1323x = \frac{1^3}{2^3} x=18x = \frac{1}{8}
