RESTA DE RADICALES
√175-√243-√ 63 -2√ 75

Answer 1

$\sqrt{175}- \sqrt{243} - \sqrt{63} -2 \sqrt{75} = \\ \\ Factorizamos \ cada \ raiz \\ \\ \sqrt{175}=\sqrt{5^2*7} = 5 \sqrt{7} \qquad\qquad \sqrt{243}= \sqrt{3^5}= 9 \sqrt{3} \\ \\ \sqrt{63}= \sqrt{3^2*7}=3 \sqrt{7} \qquad \qquad \sqrt{75}= \sqrt{5^2*3}= 5 \sqrt{3} \\ \\ Entonces \\ \\ 5 \sqrt{7} - 9 \sqrt{3} - 3 \sqrt{7}-2* 5 \sqrt{3}= \\ \\ 5 \sqrt{7} - 9 \sqrt{3} - 3 \sqrt{7}-10 \sqrt{3}= \boxed{2 \sqrt{7} -19 \sqrt{3}}$
