$\sqrt{81} =$
$\sqrt{169} =$
$\sqrt{25} =$
$\sqrt{1.024} =$
$\sqrt{2.500} =$
​

Answer 1

Explicação passo-a-passo:

a)

$\sf \sqrt{81}=\sqrt{9^2}$

$\sf \sqrt{81}=9$

b)

$\sf \sqrt{169}=\sqrt{13^2}$

$\sf \sqrt{169}=13$

c)

$\sf \sqrt{25}=\sqrt{5^2}$

$\sf \sqrt{25}=5$

d)

$\sf \sqrt{1024}=\sqrt{32^2}$

$\sf \sqrt{1024}=32$

e)

$\sf \sqrt{2500}=\sqrt{50^2}$

$\sf \sqrt{2500}=50$

Answer 2

Oie, Td Bom?!

1.

$= \sqrt{81}$

$= \sqrt{9 {}^{2} }$

2.

$= \sqrt{169}$

$= \sqrt{13 {}^{2} }$

$= 13$

3.

$= \sqrt{25}$

$= \sqrt{5 {}^{2} }$

$= 5$

4.

$= \sqrt{1024}$

$= \sqrt{32 {}^{2} }$

$= 32$

5.

$= \sqrt{2500}$

$= \sqrt{50 {}^{2} }$
