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"
