Answer 2

Answer:

C. $x=\pm\sqrt{30}$

Step-by-step explanation:

We have been given an equation $x^2=30$. We are asked to find the value of x.

To solve for x, we will take square root of both sides of our given equation as shown below:

$\sqrt{x^2}=\pm\sqrt{30}$

Using radical rule $\sqrt[n]{a^n}=a$, we will get:

$x=\pm\sqrt{30}$

Therefore, the value of x is $\pm\sqrt{30}$ and option C is the correct choice.
