Question

preciso de ajuda para responder ( 3√64-2√4/9) + √4.(9/4:1/3)+1

Answer 1

$3 \sqrt{64}-2 \sqrt{\frac{4}{9}}+ \sqrt{4}.\left(\frac{\frac{9}{4}}{\frac{1}{3}}\right)+1 =\\ \\ 3.8-2.\frac{2}{3}+2.\frac{9}{4}.\frac{3}{1}+1=\\ \\ 24-\frac{4}{3}+\frac{27}{2}+1=\\ \\ \boxed{\frac{144-8+81+6}{6}=\frac{223}{6}}$

Answer 2

=(3*8-2*2/3)+2*27/4+1=(24-4/3)+27/2+1=(72-4)/3+(27+2)/2=68/3+29/2=(136+87)/6=223/6
