Final answer:
To simplify the expression √6, we need to find two numbers that can be used for x. By rewriting the square root as a fractional power and taking the square root of both sides, we find that x = √(√6).
Step-by-step explanation:
To simplify the expression √6, we need to find two numbers that can be used for x so that the expression can be further simplified. We can start by rewriting the square root as a fractional power: x² = √6.
Next, we can take the square root of both sides of the equation: √(x²) = √(√6). This simplifies to x = √(√6).
Therefore, the two numbers that can be used for x in order to simplify the expression √6 are x = √(√6).
