Simplify each of the following:(i) \(\sqrt[3]{4}\) x \(\sqrt[3]{16}\)(ii) \(\frac{\sqrt[4]{1250}}{\sqrt[4]{2}}\) |
|
Answer» (i) \(\sqrt[3]{4}\) x \(\sqrt[3]{16}\) = \(\sqrt[3]{4\times 16}\) = \(\sqrt[3]{64}\) = \(\sqrt[3]{4^3}\) = \((4^3)^\frac{1}{3}\) = 4 (ii) \(\frac{\sqrt[4]{1250}}{\sqrt[4]{2}}\) = \(\sqrt[4]\frac{1250}{2}\) = \(\sqrt[4]\frac{625\times 2}{2}\) = \(\sqrt[4]{625}\) = \(\sqrt[4]{5^4}\) = (54)\(\frac{1}{4}\) = 5 |
