 Hi and welcome to our session. Let us discuss the following question. The question says evaluate integral of e to the power x divided by square root of 5 minus 4 into e to the power x minus e to the power 2x with respect to x. Let's now begin with the solution. Let i is equal to integral of e to the power x divided by square root of 5 e to the power x minus e to the power 2x with respect to x. The question we will put e to the power x differentiating both sides with respect to x we get equals to e to the power is equal to e to the power x into dx. So e to the power x into dx and t in place of e to the power x. Here we have t square. t plus 2 whole square is equal to sine inverse.
