Question

calculate the derivative of f(x)= (7x-11)+6[(x^.25)+13]


is the answer: 7+1.5x?

Answer 1

7 is ok, 2nd part must be 6*.25(x)^(-0.75)

Answer 2

mik.wind is right

Answer 3

can you explain why?

Answer 4

(7 x - 11) + 6 (x^(25/100) + 13)
The above simplified is:\[67+6 x^{1/4}+7 x \]The derivative of the above with respect to x is:\[7+\frac{3}{2 x^{3/4}} \]\[\int\limits \left(7+\frac{3}{2 x^{3/4}}\right) \, dx=6 x^{1/4}+7 x+c \]
