Question

Simplifique as frações .espero que vcs me ajudem

Answer 1

a) $\frac{\sqrt{120} }{\sqrt{3} }=\sqrt{\frac{120}{3}}=\sqrt{40}=\sqrt{4.10}=2\sqrt{10}$

b) $\frac{\sqrt[3]{a^{10}} }{\sqrt[3]{a^4} }=\sqrt[3]{\frac{a^{10}}{a^4} }=\sqrt[3]{a^6}=a^{6/3}=a^2$

c) $\frac{\sqrt[4]{81x^7} }{\sqrt[4]{x^3} }=\sqrt[4]{\frac{81x^7}{x^3} }=\sqrt[4]{81x^4}=\sqrt[4]{81}\sqrt[4]{x^4} =3x$

d) $\frac{\sqrt{5}.\sqrt{8} }{\sqrt{10} }=\frac{\sqrt{40} }{\sqrt{10}}=\sqrt{\frac{40}{10} }=\sqrt{4}=2$
