Entered Answer Preview Result ell (1/5)*[(e^u)/[5*([e^(2*u)]+4)]] 5 5(e241 + 4) incorrect atan(x) tan (x) incorrect (1/10)*atan((1/2)*[e^(5*x)]) tan correct 10 At least one of the answers above is NOT correct. (1 point) esx dx = du using the substitution u = e10x + 4 (1/5)*(e^u/(5(e^(2u)+ arctan(x) esx So dx = (1/10)arctan((1/(2)e^(5x))) +C 10x + 4
