Answer 3

let me see...

Answer 4

With cube and other odd roots, you can take them of negative
numbers. For example the cube root of 8 is 2 since 2^3 = 2*2*2 = 8.
What if it's the cube root of -8? Note that (-2)^3 = (-2)*(-2)*(-2) =
-8. When you multiply an odd number of negatives, the answer is
negative. That's why you can take odd roots of negative numbers.

Does this answer your question or do you know this?

Answer 5

so the answer would be B negative answers only?

@igreen help

Answer 11

should i just go with B

Answer 12

Sorry, I was dealing with something. One sec.

Answer 13

no just look at the question

Answer 14

I'd say C, actually. Because \(^3\sqrt{x}\) and \(^3\sqrt{-x}\) can have odd and even answers, I don't see how -2\(^3\) was relevant, but okay.
