Me ajudem a calcular por favor:

(olhem a foto)

Answer 1

E
$\frac{3}{5}+\frac{2}{6}=\frac{18+10}{30}=\frac{28}{30}$
Na forma reduzida:
$\frac{14}{15}$

F
$\frac{4}{3}-2+\frac{5}{2}=\frac{8-12+15}{6}=\frac{11}{6}$

G
$2^{3}*2^{4}=2^{3+4}=2^{7}=128$

H
$\frac{7^{3}}{7^{2}}=7^{3}*7^{-2}=7^{3-2}=7^{1}$

I
(-2,3)^{2}=5,29

02
$\frac{0,315}{(-5)^{2}+4^{2}}=$
$\frac{0,315}{25+16}=$
$\frac{0,315}{25+16}=$
$\frac{0,315}{41}=0,007682926829$
