Integrate 4e^x

Integrate 4e^x

To integrate 4e^x, also written as ∫4ex dx, we realise that "4" is a constant multiplier that could be taken outside of the integral.

Take the constant outside the integral.

With the numeral constant brought outside, we see that the integral is still the same but easier to perform.

e^x is simple to integrate.

We know that ∫ex dx = ex + C, which is the easiest one in calculus to perform.

Final Solution.

Finally, we multiply with the constant "4", to give the answer.
