Step-by-step explanation:
step 1. x = 27^(2/3). solve for x?
step 2. so this is the third root of 27 squared.
step 3. well 27 is 3*3*3
step 4. 27 squared is 3*3*3*3*3*3
step 5. the cube root is 1/3 of the factors. for example the cube root of 27 or 3*3*3 is 3.
step 6. the cube root of 3*3*3*3*3*3 is 3*3 or 9
step 7. answer: 9
