Algebra II Recipe: Solving Radical and Rational Exponent Equations

By G Redden

Steps to Solve an Exponent Equation
  1. Isolate the radical or exponent term.

    • If there are two radical terms, set them equal to each other.
  2. To eliminate the radical: square, cube, 4th power etc. both sides of the equation.
  3. To eliminate the exponent: raise both sides of the equation to the reciprocal of the exponent.
  4. Solve for the remaining variable using inverse operations.

    • If an x2 and x terms remain, collect all terms on the x2 side and solve the quadratic equation by one of the previous methods:

      1. Quadratic Formula
      2. Factoring
      3. Completing the Square
  5. Check your solutions by plugging them into the original equation OR where the radical or exponent term is isolated.
