Answer:
x - 2
Explanation:
We will find the fourth root of both sides, which for x⁴ is simply going to be 4. For the other side, we will need to find the 4th root of 16. This can found in one of two ways.
Take the square root of 16, which and 4, and square root it again to get 2.
Use the calculator to find the 4th root of 16, which also comes out to be 2.
Our final answer for the simplified expression is x - 2
