Answer: 4x^4
Explanation:
Firstly, let's apply the ^1/4 to the 256
The fourth root of 256 is 4, that will be the coefficient in our answer
Next, let's apply the ^1/4 to the x^16
The power of powers property says we can multiply the two exponents as so:
(x^16)^1/4 = x^(16*1/4) = x^4
Now combine the 4 and x^4 to get: 4x^4
