Final answer:
The exponential expression that is equivalent to the square root of 4x is x^(1/2)
Step-by-step explanation:
The exponential expression that is equivalent to the square root of 4x is x1/2.
This is because the square root of a number is the same as raising that number to the power of 1/2.
In this case, we have 4x, so the square root of 4x is (4x)1/2 = x1/2.
The correct answer choice is (B) x1/2.
