Answer 1

Answer:

hope this will help uh...after squaring all of them we can find the answer.

Answer 2

Answer:

$\sqrt[3]{2} \: \: \sqrt[6]{5} \: \: \sqrt[4]{7} \\ 2 {}^{ \frac{1}{3} } \: \: 5 {}^{ \frac{1}{6} } \: \: 7 {}^{ \frac{1}{4} } \\ (2 {}^{4} ) {}^{ \frac{1}{12} } \: (5 {}^{2} ) {}^{ \frac{1}{12} } \: \: (7{}^{3} ) {}^{ \frac{1}{12 } } \: \\ 16{}^{ \frac{1}{12} } \: \: 25{}^{ \frac{1}{12} } \: \: 343{}^{ \frac{1}{12} } \\ \\ therefore \\ \\ \sqrt[3]{2} < \sqrt[6]{5} < \sqrt[4]{7}$
