## Kris5 Group Title help! 4 divided by 4 + radical 7 and 3 divided by radical 5 - 2 2 years ago 2 years ago

1. JakeV8

$\frac{ 4 }{ 4 + \sqrt{7} }$

2. JakeV8

$\frac{ 4 }{ 4 + \sqrt{7} } (\frac{ 4 - \sqrt{7} }{ 4 - \sqrt{7} })$

3. JakeV8

$\frac{ 4(4-\sqrt{7}) }{ 4^{2} + 4\sqrt{7} - 4\sqrt{7} - \sqrt{7}^{2} }$

4. JakeV8

$\frac{ 16 - 4\sqrt{7} }{ 16 - 7 } = \frac{ 16 - 4\sqrt{7} }{ 9 }$
