x=16

Answer 2

Answer:

Step-by-step explanation:

To solve x^2 = 256, you can either graph it or solve it.

Graphing: Appears as a parabola that has roots at -16 and 16 on the x-axis

Solving:                                                                         x^2 = 256

square root un-does 2nd power--> (square root of x^2) = (square root of 256)

                                                                                          x = +/- 16
