 Hello and welcome to the session. I am Deepika here. Let's discuss a question which says, choose the correct answer integral of x square into e raise to power x cube dx equals a 1 by 3 e raise to power x cube plus c b 1 by 3 e raise to power x cube plus c c 1 by 2 e raise to power x cube plus c and d 1 by 2 e raise to power x square plus c. So let's start the solution. Put x cube is equal to t in the given integral. Therefore dx square dx is equal to dt. So the given integral x square into e raise to power x cube is equal to now x square dx is equal to 1 by 3 dt and x cube is equal to t. So this is equal to 1 by 3 into integral of e raise to power t dt and this is equal to 1 by 3 into e raise to power t plus c. Now substitute the value of t here and this is equal to 1 by 3 into e raise to power x cube plus c and this is our option a. So a is the correct answer. I hope the solution is clear to you. Bye and take care.
