Question

me ajudem pfv 13. Resolva a Expressão (1/5)^-2×(2/3)^3+3^-2×3^6​

Answer 1

Resposta:

$\frac{2387}{27}$

Explicação passo-a-passo:

${\frac{1}{5}}^{ - 2} = {\frac{5}{1} }^{2} = {5}^{2} = 25$

${\frac{2}{3}}^{3} = \frac{8}{27}$

${3}^{ - 2} = { \frac{1}{3} }^{2} = \frac{1}{9}$

${3}^{6} = {9}^{3} = 729$

$25 \times \frac{8}{27} = \frac{200}{27}$

+++++++

$\frac{1}{9} \times 729 = \frac{729}{9} = 81$

$\frac{200}{27} + 81 = \frac{200}{27} + \frac{2187}{27} = \frac{2387}{27}$
