Question
Having a hard time solving cubed root of 54-cubed root 16.

I'm not sure I understand this question.
I can tell you the cube root means what is multiplied together 3 times to get the answer.

For example, the cube root(8) = 2 since 2*2*2 = 8,
the cube root(27) = 3 since 3*3*3 = 27,
the cube root(125) = 5 since 5*5*5 = 125,
etc.

I'm not sure what is means by cubed root, though.  That almost sounds like finding the square root and them cubing it.

Seeing these numbers and knowing what the factors are, however, it sounds like
[cube root(54)] - [cube root(16)]?

Since 54 = 2*3*3*3 and 16=2*2*2*2, [cube root(54)] - [cube root(16)] would be
[cube root(2)]*3 - [cube root(2)]*2.

Since 3 - 2 = 1, we only have 1 cube root.  Altogether that would be cube root(2).
