Question

Help with the derivative of n^2/(1.1)^n?

Answer 1

So you have \(f(n)=\dfrac{n^2}{(1.1)^n}\).
-To get the derivative, you will need the Quotient Rule: \(\left(\dfrac{f}{g}\right)'=\dfrac{f'g-fg'}{g^2}\).
-The derivative of a power function \(n^p\) is \(p\cdot n^{p-1}\).

-The derivative of an exponential function \(a^n\) is \(\ln a \cdot a^n\).
