Question

If f(x)=3+x/4+5/x^2, find f'(x).

Answer 1

you can rewrite it as f(x) = 3 + x/4 +5x^(-2) and just use the power rule to get f'(x)

Answer 2

Use the property that derivative of sum=sum of derivatives

Answer 3

If f(x)=3+x/4+5/x^2
then f'(x)=3' + (x/4)' + [5/(x^2)]' => f'(x)= 0+(1/4)+(-10/x^3)

Answer 4

okay thanks

Answer 5
