Answer:
[tex]\frac{3\sqrt{7}}{7}[/tex]
Step-by-step explanation:
[tex]\frac{3}{\sqrt{7}}[/tex]
lets multiplty to simplify the denominator
[tex]\frac{3}{\sqrt{7}}[/tex] * [tex]\frac{\sqrt{7}}{\sqrt{7}}[/tex] = [tex]\frac{3\sqrt{7}}{\sqrt{7}*\sqrt{7}}[/tex]
now the square root of 7 times the square root of 7 makes the square root of 49, which we can simplify to 7
[tex]\frac{3\sqrt{7}}{7}[/tex]
