10- Calcule:
a) 25=
b) V121
c) V900
d) V625
e) 1600
f) V36
g) v4​

Answer 1

Explicação e Resposta

a) $\sqrt{25}=\sqrt{5\times5}=\sqrt{5^2}=5$

b) $\sqrt{121}=\sqrt{11\times11}=\sqrt{11^2}=11$

c) $\sqrt{900}=\sqrt{30\times30}=\sqrt{30^2}=30$

d) $\sqrt{625}=\sqrt{25\times25}=\sqrt{25^2}=25$

e) $\sqrt{1600}=\sqrt{40\times40}=\sqrt{40^2}=40$

f) $\sqrt{36}=\sqrt{6\times6}=\sqrt{6^2}=6$

g) $\sqrt{4}=\sqrt{2\times2}=\sqrt{2^2}=2$
