y = (lnx)

(x^{7})

Step 1

**Quotient rule of differentiation:**

If a function *f*(*x*) is a quotient of *u *and *v *where both *u *and *v *are variables then the derivative of the *f*(*x*) is obtained by the formula given below:

Step 2

**Find the derivative ( dy/dx):**

The given function is *y *= ln (*x*) / *x*7.

The derivative of *y *is obtained as (**1 -7ln( x))/(x8) **from...
