So we are working on derivatives right now... we're learning all those nifty rules to shortcut past the long formula...

derivative formula f'(x)=f(x+h)-f(x)

h

so we've learned the power rule, the product rule, the chain rule, and the quotient rule to get past the trickier versions of this equation. the only problem is i cant figure out how to do the power rule... it goes as such

if f(x)=ax^{n} then the first step of the power rule does this f'(x)=(na)x^{n-1}

and i keep forgetting where to go from there

anyone wanna help?
