how do i do this?

[slender verge]

1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

is it like one value?

my x and y are coming out to be

[night walrus]

x+y = 64^(1/6) = 4

[static latch]

,calc 64^(1/6)

[half peak]

Result:

2

[static latch]

Also:

,calc (-2)^6

[half peak]

Result:

64

[molten badge]

Yes, x+y=2

and x-y=4 (by taking root on both side)

Now solve these two equations to get x,y.

[static latch]

Not necessarily

Again, not necessarily

[hallow ibex]

hint: x+y is eather 2 or -2

x-y is eather 4 or -4
