Question 1026003: Hello, could someone please check these and see if my answers are correct? I am supposed to find the indicated real nth roots of x, if any. And, give my answers in simplest form. 1. n=6, x=-64. *no real nth roots*
2. n=3, x=128. my answer 3sqrt(128) broken down to 4 3sqrt(2).
3. n=10, x=1024. my answer is 2.
4. n=7, x=-8sqrt(2)/2187. my answer is -7sqrt(8sqrt(2)/3.
I appreciate any help! Thanks!

1. Correct.
2. Correct, I'm assuming 3sqrt stands for cube root (2^(1/3) would be clearer).
3. Partially correct, is also a solution since .
4. Correct.
