Final answer:
The function for the given equation is x^4 + 9 = 57. To find the value of x, we need to isolate x on one side of the equation. Taking the fourth root of both sides, we find that x = 2 or x = -2.
Step-by-step explanation:
The function for the given equation is x4 + 9 = 57.
To find the value of x, we need to isolate x on one side of the equation. Subtracting 9 from both sides, we get x4 = 48.
Taking the fourth root of both sides, we find that x = 2 or x = -2.
