 Hello and welcome to the session my name is Mansi and I am going to help you with the following question. The question says evaluate the following definite integral that is integral e raised to power x dx where lower limit of integration is 4 and upper limit of integration is 5. So let us start with the solution to this question. We have to evaluate the definite integral this. Now we see that integral of e raised to power x dx is equal to e raised to power x. Here the lower limit of integration is 4 and upper limit is 5. So now first of all we put x equal to 5. We have e raised to power 5 minus then we put x to be equal to 4. So we will have e raised to power 5 minus e raised to power 4 that is equal to e raised to power 4 into e minus 1. So our answer to this question is e raised to power 4 into e minus 1. So this is our answer to the question. I hope that you understood the question and enjoyed the session. Have a good day.
