Answer:
C. [tex]x=\pm\sqrt{30}[/tex]
Step-by-step explanation:
We have been given an equation [tex]x^2=30[/tex]. 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:
[tex]\sqrt{x^2}=\pm\sqrt{30}[/tex]
Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:
[tex]x=\pm\sqrt{30}[/tex]
Therefore, the value of x is [tex]\pm\sqrt{30}[/tex] and option C is the correct choice.
