Solution

Let `y = 8/(3 root3((2x^2-7x-5)^11))`

Simplify the expression using laws of exponents

`y = 8/(3(2x^2 - 7x - 5)^(11/3))`

`y = 8/3 (2x^2 - 7x - 5)^(-11/3)`

Differentiate with respect to x using Chain Rule

`dy/dx = d/dx [8/3 (2x^2 - 7x-5)^(-11/3)]`

`dy/dx = 8/3 xxd/dx [(2x^2-7x-5)^(-11/3)]`

`dy/dx = 8/3 xx (-11/3)(2x^2-7x-5)^(-11/3-1) xx d/dx(2x^2-7x-5)`

`dy/dx= -88/9 (2x^2-7x-5)^(-14/3) xx (4x-7)`

Bring the negative power to the denominator:

`dy/dx = (-88(4x-7))/(9(2x^2-7x-5)^(14/3))`

`dy/dx = (88(7-4x))/(9(2x^2-7x-5)^(14/3))`
