Problem

Solve the equation with rational exponents. \[ (x-5)^{2 / 3}=64 \] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The solution set is (Simplify your answer. Use a comma to separate answers as needed.) B. The solution set is the empty set.

Solution

Step 1 :Given the equation \((x-5)^{2 / 3}=64\).

Step 2 :Raise both sides of the equation to the power of \(3 / 2\) to get rid of the rational exponent, resulting in \(x - 5 = 64^{3 / 2}\).

Step 3 :Solve for \(x\) by adding 5 to both sides of the equation, resulting in \(x = 64^{3 / 2} + 5\).

Step 4 :Calculate the value of \(64^{3 / 2} + 5\) to get the final answer.

Step 5 :The solution set is \(\boxed{517}\).
