I found this question on another website and they factored x-8 which canceled the ((x^1/3)-8) in the denominator and then you plug 8 into the rest of the numerator to get 12. Is it not possible to just multiply numerator and denominator by (x^1/3)+2?
Homework Statement
Evaluate lim x->8 (x-8)/(cubed root of x) -2)

The Attempt at a Solution
I multiplied both numerator and denominator by (cubed root of x) +2. In the denominator, I wrote it as ((x^1/3)-2)*((x^1/3)+2) which simplifies to (x^2/3)-4. I have...
