Simplify:

(X^6)^1/2 = x^3

1000000^1/6 I don't know this one

(64n^12)^-1/6 = 1/0.5n^2

(9n^4)^1/2. = 3n^2

1000000 = 10^6, so (10^6)^1/6 = 10

(64n^12)^-1/6 = 1/2 n^2

64^-1/6 = 1/64^1/6 = 1/2, not 1/.5

.5 is already 2^-1

36^3/2 = (36^1/2)^3 = 6^3 = 216

343 = 7^3, so you have

1/7^4 = 1/2401

The others are ok
