The expression you provided seems to be incomplete or incorrectly formatted. However, I'll provide a general method to rationalize the denominator of a fraction with a square root.

Let's say we have a fraction like this: a / (b + √c)

To rationalize the denominator, we multiply the numerator and the denominator by the conjugate of the denominator. The conjugate of (b + √c) is (b - √c).

So, we multiply the fraction by (b - √c) / (b - √c), which is essentially 1.

(a / (b + √c)) * ((b - √c) / (b - √c))

This gives us:

(a * (b - √c)) / (b² - c)

Now, the denominator is a rational number.
