What is the radical form of each of the given expressions?
Lera25 [3.4K]
The main rule to apply here is:

(i) \displaystyle{ a^ {\displaystyle{ (\frac{b}{c})} }= \displaystyle{ \sqrt[c]{a^b}

(ii)If c=2, then we write the following \displaystyle{ a^ {\displaystyle{ (\frac{b}{2})} }= \displaystyle{ \sqrt{a^b}.


According to these rules:

\displaystyle{ 5^ {\displaystyle{ (\frac{2}{3})} }= \displaystyle{ \sqrt[3]{5^2}.

\displaystyle{ 5^ {\displaystyle{ (\frac{1}{2})} }= \displaystyle{ \sqrt{5^1}=\displaystyle{ \sqrt{5}.

\displaystyle{ 3^ {\displaystyle{ (\frac{2}{5})} }= \displaystyle{ \sqrt[5]{3^2}.

\displaystyle{ 3^ {\displaystyle{ (\frac{5}{2})} }= \displaystyle{ \sqrt{3^5}.

Will the opposite of zero always ,sometimes or never be zero
jek_recluse [69]
Zero is neutral. Its neither positive nor negative. Because its right in between being positive and negative.

For example: On the number line, as you can see, the opposite of a positive number such as 1 is directly the opposite of -1. But zero has no opposite numbers so it is and always will just be a neutral "0"
