Answer:
2x^2
Step-by-step explanation:
you start with √4*(x^4)
1. You know the square root of 4 is 2, therefore you get 2*√(x^4)
2. For any x value to the power of 4, its square root is x to the power of 2. Therefore you get, 2x^2.
3. To check if this is correct you can always put some value for x using √4(x^4)) and use that same x value for 2x^2, both should give you the same answer.
