((7*x^5)/(e^x))'The calculation above is a derivative of the function f (x)
((7*x^5)'*e^x-(7*x^5*(e^x)'))/((e^x)^2)
(((7)'*x^5+7*(x^5)')*e^x-(7*x^5*(e^x)'))/((e^x)^2)
((0*x^5+7*(x^5)')*e^x-(7*x^5*(e^x)'))/((e^x)^2)
((0*x^5+7*5*x^(5-1))*e^x-(7*x^5*(e^x)'))/((e^x)^2)
((0*x^5+7*5*x^4)*e^x-(7*x^5*(e^x)'))/((e^x)^2)
(35*x^4*e^x-(7*x^5*(e^x)'))/((e^x)^2)
(35*x^4*e^x-(7*x^5*ln(e)*e^x))/((e^x)^2)
(35*x^4*e^x-(7*x^5*e^x))/((e^x)^2)
(35*x^4*e^x-(7*x^5*e^x))/(e^(2*x))
