Answer:
2

Explanation:
To simplify the expression √52x^4, we can break it down as follows:
√(52x^4) = √(4 * 13 * x^4)
Since the square root of a product is equal to the product of the square roots, we can simplify further:
√(4 * 13 * x^4) = √4 * √13 * √(x^4)
The square root of 4 is 2, and the square root of x^4 is x^2:
2 * √13 * x^2
Therefore, the simplified expression is 2√13x^2.
