For this case we will show that the correct option is option C.
We find the value of the variable "x":
We apply root to both sides of the equation to eliminate the exponent:
We found the first solution with the positive value:
We use the negative value to find the other solution. Since it is an inequality, the sign of the inequality changes in the negative portion of the solution.
So, the roots are:
The solution is given by the values of "x" greater than or equal to -4 and less than or equal to 4
Answer:
Option C
