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
