Help plzz I think it is 1 or 2 By The square root property, if k is a real number and x^2=k, then what is x equal to? 1. √k 2. =| √k 3. -√k 4. k^2

Step-by-step explanation:

k is a real number.

We take the square root of both sides of the equation.

Simplifying the equation.

x = ±√k

Step-by-step explanation:

If:

We'll take square root on both sides

=>

=> x = ±√k
