Question

calcule o valor da expressão:
√9/16 - √625/144 + √49-64 - √16/8

Answer 1

$\sqrt{ \frac{9}{16} }- \sqrt{ \frac{625}{144} }+ \sqrt{49}-64- \sqrt{ \frac{16}{8} }=$

$\frac{3}{4}- \frac{25}{12}+7-64- \sqrt{2}=$ --->mmc(4,12)=12

$\frac{9-25+84-768}{12}- \frac{12 \sqrt{2} }{12}=$

$\frac{-700}{12}- \frac{12 \sqrt{2} }{12}=- \frac{175}{3}- \sqrt{2}$
