Odd and even roots gre review book


Hi team,
can anyone please help me understand this statement.

All in all you can take the even roots of the positive number only while with odd roots you can have both negative and positive numbers.

So you mean that if ive even root like underroot of 6 or 8 i can only take positive whereas ee can take both for odd roots like 7, 9 etc did i understood correctly

if you have an integer let say 5 : then

for odd order root

\sqrt[x]{5}, \text{where x = 1,3,5,7....}

\text{when 'x' is any odd integer, we will only have one root even if we change the positive 5 to - 5.}

\sqrt[x]{5},\text{where x = 2,4,6,8...}

\text{But if 'x' is even then we will have two roots in-case of positive 5 and no roots in-case of -5.}

Thank you!!!.
