((-3/(x^2))/8)'The calculation above is a derivative of the function f (x)
((-3/(x^2))'*8-((-3/(x^2))*(8)'))/(8^2)
((((-3)'*x^2-(-3*(x^2)'))/((x^2)^2))*8-((-3/(x^2))*(8)'))/(8^2)
(((0*x^2-(-3*(x^2)'))/((x^2)^2))*8-((-3/(x^2))*(8)'))/(8^2)
(((0*x^2-(-3*2*x^(2-1)))/((x^2)^2))*8-((-3/(x^2))*(8)'))/(8^2)
(((0*x^2-(-3*2*x))/((x^2)^2))*8-((-3/(x^2))*(8)'))/(8^2)
(6*x^-3*8-((-3/(x^2))*(8)'))/(8^2)
(6*x^-3*8-((-3/(x^2))*0))/(8^2)
(3*x^-3)/4
