Question

The bottom number. I need written in a way where there is no number above the square root symbol. (The number 4 that’s a live the square root symbol) I need it like simplified to where there is no number above the square root symbol

Answer 1

`(18\sqrt[4]{5})^8=18^8\sqrt[]{25}`

1) Let's rewrite that radical, in a way that we can eliminate the fourth root:

`18\sqrt[4]{5}\Rightarrow(18\sqrt[4]{5})^8=18^8\cdot(\sqrt[4]{5})^8=18^8\text{ }\sqrt[]{25}`

2) This way we can get rid of the fourth root by raising to the power (in this case 8) as the index of the root (4).

3) Hence, one possible way to rewrite it with no root is

`(18\sqrt[4]{5})^8=18^8\sqrt[]{25}`
