Step 2 contains a mistake from the previous step.
The correct step 2 should be:
Step 2 - (3^3 x 3^-2) / (3^6)^2 = (3^3 x 3^-2) / 3^12
Here, we need to apply the exponent rule that states: (a^m)^n = a^(m x n).
So, the correct step 2 should be:
(3^3 x 3^-2) / 3^12 = (3^3 x 3^-2) / 3^12 = 3^(3 - 2 - 12) = 3^-11.
