​

Answer 1

Resposta:

$\sqrt{7..552}$

$\sqrt{696}$

Answer 2

a) $/\frac{\sqrt[2]{12\sqrt[2]{9} } }{5} /= /\frac{\sqrt[2]{12-3} }{5} / =/\frac{\sqrt[2]{9} }{5} /= /\frac{3}{5} / = \frac{3}{5}$

b) $/\frac{12}{4} - \frac{23}{3} /= /\frac{36-92}{12} /= /-\frac{56:4}{12:4} /-\frac{14}{3} / = -\frac{14}{3} . (-1) = \frac{14}{3}$
