Gien the expression:
[tex]\frac{3}{\sqrt{7}}[/tex]Let's simplify the expression.
To simplify, let's rationalize the denominator.
We have:
[tex]\frac{3}{\sqrt{7}}*\frac{\sqrt{7}}{\sqrt{7}}[/tex]Now, we have:
[tex]\begin{gathered} \frac{3\sqrt{7}}{\sqrt{7}*\sqrt{7}} \\ \\ =\frac{3\sqrt{7}}{7} \end{gathered}[/tex]Therefore, the simplified expression is:
[tex]\frac{3\sqrt{7}}{7}[/tex]ANSWER:
[tex]\frac{3\sqrt{7}}{7}[/tex]
