Find the derivative of ln (x^3 +9)/x^3 +9 Find the derivative of ln (x^3 +9)/x^3 +9 @Mathematics

Answer 1

27/(x(10x^3+9))

Answer 2

why is it 27 on the numerator?

Answer 3

first lets simplify the eq given in log function, write it as 10+(9/x^3)..
the coefficient of x when multiplied with 9 when the ln function is differentiated gives 27 in the numerator..
