Answer 1

$\frac{( \sqrt{5} + 2 \sqrt{3} ) - 17}{ \sqrt{15} }$

$\frac{ \sqrt{5} + 2 \sqrt{3} - 17 }{ \sqrt{15} } \times \frac{ \sqrt{15} }{ \sqrt{15} }$

$\frac{ \sqrt{75} + 2 \sqrt{45} - 17 \sqrt{15} }{15}$

$\frac{5 \sqrt{3} + 6 \sqrt{5} - 17 \sqrt{15} }{15}$

$\frac{ - 43.76405}{15}$

$- 2.9176$
