Please check my answers on the following questions

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

36^3/2 = my answer is 2 in the index of the aware root of 36^3

343^-4/3 I don't know this one

Thanks

Square root**
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
