Olá! ^-^

1) a)

$\frac{\sqrt{4} }{\sqrt{9} }- \frac{1}{3} \\\frac{2}{3} -\frac{1}{3} \\\frac{2-1}{3} \\\frac{1}{3}$

b)

$\frac{3}{\sqrt{25} } +2\\\frac{3}{5}+\frac{2}{1} \\\frac{3+10}{5} \\\frac{13}{5}$

c)

$\frac{7}{\sqrt{16} } - \sqrt{1} \\\frac{7}{4} -\frac{1}{1} \\\frac{7-4}{4} \\\frac{3}{4}$

d)

$\frac{\sqrt{9} }{4} -\frac{1}{2} \\\frac{3}{4} -\frac{1}{2} \\\frac{3-2}{4} \\\frac{1}{4}$

10)  $(\frac{8}{5})^{+1}= \frac{8}{5}$ --> d) n.d.a.

Espero ter ajudado! <3
