Question

Calcule: (\/-25+4•\/-9)•2-\/-36:\/-1•5

Obs: \/-= Raiz quadrada

Answer 1

$( \sqrt{25}+4. \sqrt{9}).2- \sqrt{36}: \sqrt{1}-5=\\ \\ (5+4.3).2-6:1-5=\\ \\ (5+12).2-6-5=\\ \\ 17.2-11=\\ \\ 34-11=23$$( \sqrt{25}+4. \sqrt{9}).2- \sqrt{36}: \sqrt{1}-5=\\ \\ (5+4.3).2-6:1-5=\\ \\ (5+12).2-5-5=\\ \\ 17.2-10=\\ \\ 34-10=24$
