7. o valor da expressão é:

Answer 1

$\frac{4^3.2^{-3}+\left(\frac{1}{3}\right)^{-4}.3^{-2}}{5.\left(1,2\right)^{-1}} \\\\\frac{64.\frac{1}{2^3}+\left(\frac{3^4}{1}\right).\frac{1}{3^2}}{5.\left(\frac{12}{10}\right)^{-1}}\\\\\frac{64.\frac{1}{8}+\left(81\right).\frac{1}{9}}{5.\left(\frac{10}{12}\right)}\\\\\frac{\frac{64}{8}+\frac{81}{9}}{\left(\frac{5.10}{12}\right)}\\\\\frac{8+9}{\left(\frac{50}{12}\right)}\\\\\frac{17.12}{50}\\\\\frac{204}{50}\\\\\frac{102}{25}=4,08$
