Question

1) De acordo com as informações do quadro calcule o valor aproximado de:√6=2,45√7=2,65√11=3,32a) √44+2√99b) 2√24-√54c) -√252+√28d) -√96+√11-3√112

Answer 1

$\sqrt{44} +2 \sqrt{99} =26,53$
$2\sqrt{24} - \sqrt{54}=2,45$
$- \sqrt{252} + \sqrt{28} =-10,58$
$- \sqrt{96}+ \sqrt{11-3} \sqrt{112}= 20,14$
