The simplest radical form of (sqrt(7))/sqrt(11) is (sqrt(77))/11.

Explanation:

To write this type of expression in simplest radical form, we must begin by rewriting it so that the denominator is not an irrational number. This process is called "rationalizing the denominator..' Consider sqrt(11). This is an irrational number, and to be able to replace this denominator with a rational number, it needs to be multiplied by itself. However, we can't just introduce sqrt(11) to the denominator. Therefore, we will multiply both the numerator and the denominator by sqrt(11).

(sqrt(7))/sqrt(11) * (sqrt(11))/sqrt(11) = (sqrt(77))/sqrt(121) = (sqrt(77))/11

This is the simplest radical form of (sqrt(7))/sqrt(11).
