Question

HELP PLEASE!

Answer 1

D

Answer 2

look at the degres of the root

Answer 3

it is odd

Answer 4

thank you!!!

Answer 5

@RH I think the answer is not D but I need to check a theorem.

Answer 6

@Directrix, it is D, try for example this: (-2)*(-2)*(-2)=-8

Answer 7

\[\sqrt[3]{-8}\]=-2

Answer 8

thank you guys for helping!

Answer 9

I agree with that. It is the exponent that I am trying to remember - what happens order of operation wise. I can't prove anything or find the theorem just yet so @RH and @SerikMB ignore my comments.

Answer 10

@Directrix, the matter here is in the degree of the root

Answer 11

if it is even, then it will convert it into positive, you are probably here confusing with complex numbers. Where the degree is even and you have - in the root. But when the degree is odd then "-" in the root is ok

Answer 12

@Directrix

Answer 13

I see. Thanks.

Answer 14

Thank you a lot guys for explaining that :)

Answer 15

Thanks for your patience @RH .
