Step 2 had the mistake.  It should have been 3^2 =9

Step 3 had the mistake.  It should have been 3−2 = 1^−2 = 1

There is no mistake.  The answer is correct.

Step 1 had the mistake.  It should have been  (6^−4)^4/3^6

Step 1 had the mistake. It should have been (3^3 * 2^−4)^4 / 3^6 = (3^12 * 2^−16) / 3^6.
