Answer 1

Explicação passo-a-passo:

a) $\sf \sqrt{18}$

$\sf =\sqrt{3^2\cdot2}$

$\sf =3\sqrt{2}$

b) $\sf \sqrt{92}$

$\sf =\sqrt{2^2\cdot23}$

$\sf =2\sqrt{23}$

c) $\sf \sqrt{50}$

$\sf =\sqrt{2^2\cdot5}$

$\sf =2\sqrt{5}$

d) $\sf \sqrt{27}$

$\sf =\sqrt{3^2\cdot3}$

$\sf =3\sqrt{3}$

e) $\sf \sqrt{44}$

$\sf =\sqrt{2^2\cdot11}$

$\sf =2\sqrt{11}$

f) $\sf \sqrt{20}$

$\sf =\sqrt{2^2\cdot5}$

$\sf =2\sqrt{5}$

g) $\sf \sqrt{56}$

$\sf =\sqrt{2^2\cdot2\cdot7}$

$\sf =2\sqrt{14}$

h) $\sf \sqrt{60}$

$\sf =\sqrt{2^2\cdot3\cdot5}$

$\sf =2\sqrt{15}$

i) $\sf \sqrt{96}$

$\sf =\sqrt{2^4\cdot2\cdot3}$

$\sf =4\sqrt{6}$

j) $\sf \sqrt{63}$

$\sf =\sqrt{3^2\cdot7}$

$\sf =3\sqrt{7}$
