## anonymous 4 years ago X^2+4/x differentiate, confused on how to arrange this

1. anonymous

you have to find the derivative, you use the power rule i just am confused on what goes where,

2. phi

x^2 + 4*x^-1

3. phi

the rule is $\frac{d x^n}{dx}= n x^{n-1}$

perfect thank you, so you just basically apply the x in the denominator to the outside 4 in this one. I got ya thanks again

5. phi

you should get $2 x -4x^{-2}$ or $2 x - \frac{4}{x^2}$
