Question

Efetue cada multiplicação e simplifique
o resultado.
a) V8 V6 d) 2/10 . 530
b) √ √27 e 8 /12 - 10/3
c) √2 √28 f) 6/7.5/2.8/21​

Answer 1

Resposta:

a) $\sqrt{8} \sqrt{6} = \sqrt{48} = \sqrt{4.4.3} = 4\sqrt{3}$

b) $\sqrt{\sqrt{27} } = \sqrt[4]{27}$

c) $\sqrt{2}\sqrt{28} = \sqrt{56} =\sqrt{14.4} = 2\sqrt{14}$

d) $\frac{2}{10}.530 = 2.53 = 106$

e) $\frac{8}{12} -\frac{10}{3} = \frac{2}{3}-\frac{10}{3} = -\frac{8}{3}$

f) $\frac{6}{7}. \frac{5}{2}. \frac{8}{21} = \frac{240}{294} = \frac{40}{49}$
