To evaluate the expression, let's break it down step by step:
Step 1: Evaluate one-third cubed.
(1/3)^3 = 1/27
Step 2: Evaluate one-third raised to the zero power.
(1/3)^0 = 1
Step 3: Multiply the results from steps 1 and 2.
(1/27) * 1 = 1/27
Step 4: Raise the result from step 3 to the second power.
(1/27)^2 = 1/729
Therefore, the quantity (1/3)^3 * (1/3)^0, all raised to the second power, is equal to 1/729.
Hence, the correct answer is "one over 729."
