find d/dx x^3/3. I don't know how to differentiate fractions.

OpenStudy (anonymous):

( x³)' = ..?

OpenStudy (anonymous):

Why it takes soooooo long?!?

OpenStudy (anonymous):

\[\frac{ d}{ dx}\frac{ x ^{3}}{ 3}\]

OpenStudy (anonymous):

Answer right to my question, will you? ( x³)' = ..?

OpenStudy (anonymous):

do you agree that it is the same as (1/3)x^3

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Then do it the same way. bring the exponent in front and subtract -1 like normal

OpenStudy (anonymous):

what about the constant? would d/dx x^3 times zero be zero?

OpenStudy (anonymous):

nevermind i just figured it out
