Find the derivative for each of the following functions. please show steps, thank you

a. f (x) = x6 b. f ( x ) = 8 c. f ( x) = - 1 X' d. f ( x ) = x3 e. f (x) = x , hint: write radicals IN exponential form first THEN apply power rule. f. f ( x ) = Vx3 9. f ( x ) = 3/x2 hint: write radical in exponential form s.t. (such that) you do NOT have a rational expression! h. f (x) = 1 VX
