Question #N246
What is the value of $x$ in the equation $x^2 = 16$?
A. -8
B. -4
C. 4
D. 8
Correct Answer is: C
The equation $x^2 = 16$ means that we are looking for a number that, when multiplied by itself, equals 16. The positive square root of 16 is 4, so $x = 4$ is a solution. The negative square root of 16 is also a solution, but since the problem only asks for the value of $x$, we can disregard the negative solution.
