Question

When the nth root of a is written, it is the positive value that is shown

Answer 1

\(\Large\color{red}{ \bf \sqrt[n]{a} }\) is always positive, unless, ` a < 0 ` and "n" is an odd number.

Answer 2

Solomon is right

Answer 3

if ` a < 0 ` and "n" is an even number, then it's an imaginary number.

Answer 4

if ` a < 0 ` , then whether "n" is odd or even, it's a positive number.

Answer 5

As a side note: For any natural \(n\) and complex \(a\), \(\sqrt[n]{a}\) can take on more than one complex value.
