Question

For what real values of X is the cubed root > than X?

Answer 1

Please help! I have no idea how to do this problem!!

Answer 2

If X is smaller than -1, it will be true (the number will be nearer 0). If x is < 1 but > 0, it will also be true. I don't think that there are other intervals left.

Answer 3

Could you please state the problem more clearly? For what values of x is the cube root of what greater than x?

Answer 4

Assuming you mean the cubic root of x.

Answer 5

\[\sqrt[3]{x}>x\]

Answer 6

yes

Answer 7

\[x-x ^{\frac{1}{3}}<0^{}\]
\[x ^{\frac{1}{3}}(x ^{\frac{2}{3}}-1)>0\]

Answer 8

Now make pictures of the factors and see where the product is positive.
