your problem i mean...

anonymous · Answer

yes

anonymous · Answer

just like in algebraic expressions we have like terms here...
the cube roots are all like terms
and
the 4th roots are all like terms
can you combine them?

would it be -5 square root of 7?

anonymous · Answer

no.. your answer will be in terms of cube roots and 4th roots.

anonymous · Answer

let's try it this way...:
let x=cube root 7
let y= fourth root 7

so the problem is like this:  10x - 7y - 9x + y
can you simplify that?
