Answer 1

Respuesta:

  $\cfrac{~9\sqrt{2~}-8\sqrt{3~}~}{6}$

Explicación paso a paso:

• Sabemos que:

            $\cfrac{~\pi~}{6}=30^o$

• Entonces tendremos:

                $3\sin (45^o)-4\tan (\cfrac{~\pi~}{6})\\\\3\sin (45^o)-4\tan (30^o)\\\\3( \cfrac{~\sqrt{2~}~}{2})-4(\cfrac{~\sqrt{3~}~}{3})\\\\\\\cfrac{~3\sqrt{2~}~}{2}-\cfrac{~4\sqrt{3~}~}{3}\\\\\\\cfrac{~3(3\sqrt{2~})-2(4\sqrt{3~})~}{6}\\\\\\\cfrac{~9\sqrt{2~}-8\sqrt{3~}~}{6}$
