Actually, you need to know these tables as the multiplication table . . . 


<pre>
If f(x) = {{{e^x}}} + {{{x^e}}},  then


   f'(x) = {{{e^x}}} + {{{e*x^(e-1)}}}.



Regarding your first function, I can not distinct between


y = - ln(x^4) + {{{e^7}}}   and   y = - (ln(x))^4 + {{{e^7}}}.


Use parentheses to make your formulas unambiguous.
