Solve Rational Radical Absolute Value

• Step 1: Squaring does not cancel a square root. Squaring and square-rooting are not inverse operations.

• Step 2: The cubed root of 64 is 4, not 8.

• Step 3: We should add 5 to both sides of the equation, not subtract 5.

• Step 4: Taking a square root, or any even root, does not require both the positive and negative root.

• There is no error - the equation is solved correctly.
