Question

Responder somente quadro B mas completo

Answer 1

Oie, tudo bom?

Somente o cartão B.

a)

$= 5 \sqrt{25} \\ = 5 \: . \: \sqrt{5 {}^{2} } \\ = 5 \: . \: 5 \\ \boxed{ = 25}$

b)

$= \sqrt{0,25} \\ = \sqrt{0,5 {}^{2} } \\ \boxed{ = 0,5}$

c)

$= \sqrt{1,44} \\ = \sqrt{1,2 {}^{2} } \\ \boxed{ = 1,2}$

d)

$= \sqrt[3]{0,027} \\ = \sqrt{0,3 {}^{3} } \\ \boxed{ = 0,3}$

e)

$= 2 \sqrt{6,25} \\ = 2 \sqrt{2,5 {}^{2} } \\ = 2 \: . \: 2,5 \\ \boxed{ = 5}$

f)

$= 10 \sqrt[3]{0,001} \\ = 10 \sqrt[3]{0,1 {}^{3} } \\ = 10 \: . \: 0,1 \\ \boxed{ = 1}$

g)

$= - \frac{1}{2} \sqrt{0,04} \\ = - \frac{1}{2} \sqrt{0,2 {}^{2} } \\ = - 0,5 \: . \: 0,2 \\ \boxed{ = - 0,1}$

h)

$= 0,3 \sqrt{1,21} \\ = 0,3 \sqrt{1,1 {}^{2} } \\ = 0,3 \: . \: 1,1 \\ \boxed{ = 0,33}$

i)

$= 2 \sqrt[4]{ \frac{1}{16} } \\ = 2 \sqrt[4]{0,0625} \\ = 2 \sqrt[4]{0,5 {}^{4} } \\ = 2 \: . \: 0,5 \\ \boxed{ = 1}$
