Question

Julgue os itens em certo (C) ou errado (E).
a) ( )11/√11= √11
b) ( )8/√3= 8√3/3
c) ( )5√2/√6= 5√12

Answer 1

Olá,Boa noite!!!

$a(c) \frac{11}{ \sqrt{11} } \times \frac{ \sqrt{11} }{ \sqrt{11} } = \frac{11 \sqrt{11} }{11} = \sqrt{11} \\ \\ b)(c) \frac{8}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{8 \sqrt{3} }{3} \\ \\ c)(e) \frac{5 \sqrt{2} }{ \sqrt{6} } = \frac{5}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{5 \sqrt{3} }{3}$

Espero ter ajudado!!!
