 Welcome to the session. Let us discuss the following question. The question says, integrate the following functions f dash a x plus b into f of a x plus b to the power n. Let's now begin with the solution. Let i is equal to integral of f dash a x plus b into f of a x plus b to the power n with respect to x. Now put of a x plus b as t. This implies f dash a x plus b into a is equal to dt by dx. This implies dash a x plus b into dx is equal to dt by a. So by substituting in place of f of a x plus b and dt by a in place of f dash a x plus b dx, we get i as integral of with respect to t into 1 by a. We know that integral of x to the power n with respect to x is equal to x to the power n plus 1 by n plus 1 plus c. So using this formula, integral of t to the power n with respect to t is equal to n plus 1 by n plus 1 plus c. Now t is equal to, this is equal to 1 by a into plus b to the power n by n plus 1 plus c. Be patient. Bye and take care.
