Answer 1

$a) \sqrt{a^8} = a^4\\ b) \sqrt[3]{x^{15}}= x^5\\ c) \sqrt{a^2x}= \sqrt{a^2}\cdot\sqrt{x}=\sqrt{x}=\\ d) \sqrt[4]{2^4\cdot5}= \sqrt[4]{2^4}\cdot\sqrt{5}=2\sqrt[4]{5}=\\ e) \sqrt{3^2\cdot7^2\cdot5}= \sqrt{3^2}\cdot\sqrt{7^2}\cdot\sqrt{5}=3\cdot7\cdot\sqrt{5}=21\sqrt{5}\\ f) \sqrt[5]{a^5\cdot x^2 \cdot y^5}= \sqrt[5]{a^5}\cdot\sqrt[5]{x^2}\cdot\sqrt[5]{y^5}= a\cdot\sqrt[5]{x^2}\cdot y=ay\sqrt[5]{x^2}$ [/tex]
