Subtracting 9 from both sides of this equation yields 16= 2 =! x . Taking the square root of each side of this equation yields x 4. It =25 - follows that g^xh when the value of x is 4 or 4. Only 4 is listed among the choices. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors.
