To rationalize the denominator in this case, we'll need to eliminate any square roots or irrational numbers from the denominator. Since you haven't provided a specific expression, I'll assume you're referring to a fraction where the denominator contains a square root.
Let's say the expression is:
\[ \frac{1}{\sqrt{2}} \]
To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator, which is \(\sqrt{2}\):
\[ \frac{1}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \frac{\sqrt{2}}{2} \]
So, the rationalized form of the expression \( \frac{1}{\sqrt{2}} \) is \( \frac{\sqrt{2}}{2} \).
If this is not the expression you were referring to, please provide more details so I can assist you further.
