I don't know what that is, so I'll just keep that as the cube root, well, we could leave it as 5 to the 1/4, and that's not not simplified. or we can just rewrite it again as the fourth root of 5. a to the fourth to the 1/4 power: if your raise something to a power and then another power, and raise that to another power, that's equivalent of raising a to the four times 1/4 power.
