solve the equation x^2 = 256. What is the principal square root of 256

1 answer

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
