A.
[tex] \sqrt{ \frac{1}{3} } = \frac{ \sqrt{1} }{ \sqrt{3} } = \frac{ \sqrt{1} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{ \sqrt{3} }{3} = \frac{1}{3} \sqrt{3} [/tex]
B.
[tex] \sqrt{ \frac{1}{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{ \sqrt{2} }{2} = \frac{1}{2} \sqrt{2} [/tex]
C.
[tex] \sqrt{ \frac{3}{5} } = \frac{ \sqrt{3} }{ \sqrt{5} } = \frac{ \sqrt{3} }{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{ \sqrt{15} }{5} = \frac{1}{5} \sqrt{15} [/tex]
D.
[tex] \sqrt{ \frac{1}{7} } = \frac{ \sqrt{1} }{ \sqrt{7} } = \frac{ \sqrt{1} }{ \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{ \sqrt{7} }{7} = \frac{1}{7} \sqrt{7} [/tex]
E. ³√2/3 = 21/3 / 31/3 = 2/3
