Answer 1

We are given the following radical

`\sqrt[]{243}`

Let us reduce the above radical

We need to break the number 243 into a product of factors

Notice that 81 and 3 are the factors (83×3 = 243)

`\sqrt[]{243}=\sqrt[]{81}\cdot\sqrt[]{3}`

Since 81 is a perfect square so the radical becomes

`\sqrt[]{243}=\sqrt[]{81}\cdot\sqrt[]{3}=9\cdot\sqrt[]{3}`

Therefore, the simplified radical is
