Answer 1

Explicação passo-a-passo:

a)

$\sf \sqrt[6]{64}=\sqrt[6]{2^6}=\red{2}$

b)

$\sf \sqrt{225}+\sqrt{121}-\sqrt{81}$

$\sf =15+11-9$

$\sf =26-9$

$\sf =\red{17}$

c)

$\sf \sqrt[3]{27}\cdot\sqrt[3]{125}$

$\sf =3\cdot5$

$\sf =\red{15}$

d)

$\sf \sqrt[4]{16}+\sqrt[4]{81}+\sqrt[4]{256}$

$\sf =2+3-4$

$\sf =5-4$

$\sf =\red{1}$

f)

$\sf \sqrt{0,0121}+\sqrt{0,0144}+\sqrt{0,0225}$

$\sf =0,11+0,12+0,15$

$\sf =0,23+0,15$

$\sf =\red{0,38}$
