So, in this question we have integration that is e lower limit and upper limit e raise to 4, 1 divided by x under root ln x dot dx equal to means that we have to find that we have to find.
00:22
So, what we have to do? so, let us assume that ln x will be our m.
00:29
So, if we differentiate this first equation, then we get that is if we differentiate this ln x it will be 1 divided by x dot dx equal to dm.
00:45
Now let us say our x is equal to e.
00:56
So, if we differentiate then it will be if we differentiate with means if we multiply logarithmic on both the side, then we will get that is ln x equal to 1 and this ln x is what our m.
01:14
Similarly, if we equate x is equal to e raise to 4 and if we differentiate means if we multiplying ln on both the side, then ln x equal to 4 equal to m...
