Answer 1

Resolvendo, teremos:

5². 2³/3³ + 1/3² . $3^{5}$

25 . 8/27 + 1/9 . 243

200/27 + 243/9

MMC
27,9
9,3
3,1
1,1

mmc: 3.3.3 = 3³ = 27

200/27 + 243.3/27

729+200/27

Resposta: aprox. 34

Answer 2

$( \frac{1}{5} )^{-2} *( \frac{2}{3} )^{3} +3^{-2} *3^{5}$
$=(5)^{2}* \frac{8}{27} +3^{-2+5}$
$=25* \frac{8}{27} +3^{3}$
$= \frac{200}{27} + 27$
$= \frac{200+27*27}{27}$
$= \frac{200+729}{27}$
$= \frac{929}{27}$
$=34,40$
