Your formatting is unclear. What is the "cubed root"? Is this the cube of a square root? Which bits are inside this root? Is just the "1" in the numerator of the fraction? Is just sqrt[x] in the denominator? :?

When you reply with clarification of the expression, please also show your work and reasoning so far, so we can "see" where you are having trouble. Thank you! :wink:

Okay, so the expression is as follows:

. . . . .\(\displaystyle \sqrt[3]{x}\, -\, \frac{1}{\sqrt{x}}\, -\, 1\)

But what are you supposed to do with this? What were the instructions? How far did you get? Where are you stuck?

Please be complete. Thank you! :wink:
