Question

simplifique os seguintes radicais:

Answer 1

$e) \sqrt[3]{x^6y^9z^{12}}\\ \sqrt[3]{x^3\cdot x^3\cdot y^3\cdot y^3\cdot y^3\cdot z^3\cdot z^3\cdot z^3\cdot z^3}\\ x\cdot x\cdot y\cdot y\cdot y\cdot z\cdot z\cdot z\cdot z\\ \boxed{x^2y^3z^4}\\\\ f)\sqrt{\dfrac{16a^8b}{4}}=\sqrt{4a^8b}\\ \sqrt{2^2a^2a^2a^2a^2b}=2\cdot a\cdot a\cdot a\cdot a\cdot \sqrt{b}\\ \boxed{2a^4\sqrt{b}}$
