# Thread: Derivatves of y= X^150 = what ?

1. ## Derivatves of y= X^150 = what ?

Hi all

Derivatves of y= X^150 = what ?

Are the answer wil be :

y^150 = 0

or y^150 = 150!

If we derive with respect to x then use the standard power rule.

If $y = x^n$ (where n is a constant) then $\frac{dy}{dx} = nx^{n-1}$

If you need any more help post what you've done

Hi

I now that rule but the teacher say

y^150 = 0

or y^150 = 150!

I don't now what he mean ?

4. I viewed your other post in calculus and I believe you have some mis-understanding.
1. Why are you shifting 150 to y?
2. Define your definition of a derivative.
What are 'Derivatives?"

Because the only definition I can derive is $\frac{dy}{dx}$

And if that is the definition you speak of, I would most likely say your teacher is wrong... Unless I am mistaken

5. ## Guessing

I believe your teacher is asking what you're left with after you take the derivative 150 times.
