 $\frac{\sqrt{3}}{\sqrt{12}}\ is\ the\ same\ as\ \sqrt{\frac{3}{12}}$  

• True

• False

After multiplying by the conjugate, you will have:

• $\frac{21\ -7\sqrt{15}}{-6\ +\ 6\sqrt{15}}$

• $\frac{21\ -\ \sqrt{105}}{-6}$

• $\frac{21\ -\ 7\sqrt{15}}{9\ -\ 3\sqrt{15}\ +\ 3\sqrt{15}\ -\ 15}$

• $\frac{21\ -\ 7\sqrt{15}}{9\ -\ \sqrt{15}}$
