Question

$\frac{ \sqrt{2} }{2} - \frac{5}{ \sqrt{2} } \times \frac{3}{ \sqrt{6} } - { \sqrt{6} }^{2} + 6$
​

Answer 1

Răspuns:

$\frac{\sqrt{2}-5\sqrt{3} }{2}$

Explicație pas cu pas:

$\frac{\sqrt{2} }{2} -\frac{5}{\sqrt{2} } *\frac{3}{\sqrt{6} } -\sqrt{6} ^2+6=$

$\frac{\sqrt{2} }{2} -\frac{5}{\sqrt{2} } *\frac{3}{\sqrt{6} } -6+6=$

$\frac{\sqrt{2} }{2} -\frac{5}{\sqrt{2} } *\frac{3}{\sqrt{6} } =$

$\frac{\sqrt{2} }{2} -\frac{15}{\sqrt{12} } =$

$\frac{\sqrt{2} }{2} -\frac{15}{2\sqrt{3} } =$

$\frac{\sqrt{2} }{2} -\frac{15\sqrt{3} }{2*3} =$

$\frac{\sqrt{2} }{2} -\frac{5\sqrt{3} }{2} =$

$\frac{\sqrt{2}-5\sqrt{3} }{2}$
