OpenStudy (anonymous):
\[\frac{\sqrt {81}}{ \sqrt {7}} =\frac{\sqrt {9*9}}{ \sqrt {7}}\]

OpenStudy (anonymous):
good job you are right\[\frac{9 }{ \sqrt {7}}\]
OpenStudy (amistre64):
\[\frac{9\sqrt7}{7}=\frac{9}{\sqrt7}\]
\[\frac{\sqrt7}{7}=\frac{1}{\sqrt7}\]
\[\frac{\sqrt7\sqrt7}{7\sqrt7}=\frac{1}{\sqrt7}\]
\[\frac{7}{7\sqrt7}=\frac{1}{\sqrt7}\]
\[\frac{1}{\sqrt7}=\frac{1}{\sqrt7}\]

OpenStudy (anonymous):
That's why I don't trust answer choices....
