The equation is x^2 = 256, which means we need to find the value of x that, when squared, equals 256.
Taking the square root of both sides of the equation, we get:
√(x^2) = √256
Simplifying further, we get:
x = ±√256
The principal square root is the positive square root. Therefore, the principal square root of 256 is:
x = √256 = 16
solve the equation x^2 = 256. What is the principal square root of 256
