Answer:
The fourth root of -16/81, whose result is -0.19, is -0.66.
Explanation:
To determine the fourth root of -16/81, you must first perform this mathematical operation, and then perform the radication of the result of it. Thus, the following process must be carried out:
-16 / 81 = X
-0.19 = X
4√0.19 = -X
0.66 = -X
-0.66 = X
Therefore, the fourth root of -16/81, whose result is -0.19, is -0.66.
