Example 8 Video Example ) Differentiate y = x7Vx. Solution 1 Since both the base and the exponent are variable, we use logarithmic differentiation. In(y) = In(x7vx) = 7Vx In(x) y' + (In(x)) · = 7 In(x) = y - Solution 2 Another method is to write x7Vx = eln(x) 7Vx xp xp d dx (as in Solution 1) Need Help? Read It
