Question

7/2 sqrt 11 - 4/3 sqrt 7 - 5/6 sqrt 11 + -9/4 sqrt 7 + sqrt 7

Answer 1

$\frac{7}{2} \sqrt{11} - \frac{4}{3} \sqrt{7} - \frac{5}{6} \sqrt{11} - \frac{9}{4} \sqrt{7} + \sqrt{7}$
sumo términos semejantes
$( \frac{7}{2} - \frac{5}{6} ) \sqrt{11} +( \frac{-4}{3} - \frac{9}{4} +1) \sqrt{7}$
$\frac{32}{12} \sqrt{11} +( \frac{-16}{12} - \frac{27}{12} + \frac{12}{12} ) \sqrt{7}$
simplifico
$\frac{8}{3} \sqrt{11} +( \frac{-31}{12} \sqrt{7} )$
elimino paréntesis
$\frac{8}{3} \sqrt{11} -\frac{31}{12} \sqrt{7} /////respuesta$

Espero te sirva
