A curve has the equation y= 12 + x^2 (root)x / x , x > 0

a) express the equation in the form 12x^p + x^q

b) I) hence find dy/dx

ii) find an equation of the normal to the curve at the point on the curve where x=4

iii) the curve has a stationary point P. Show that the x-coordinate of P can be written in the form 2^k, where k is a rational number
