 Hi, and welcome to the session. I am Deepika here. Let's discuss the question, differentiate the following function with respect to x. x plus 3 whole square into x plus 4 whole cube into x plus 5 is to power 4. Let's start the solution. Let y is equal to given function x plus 3 whole square into x plus 4 whole cube into x plus 5 raised to power 4. Therefore, taking logarithm on both sides, we get log y is equal to log m raised to power n is equal to m log m and log of m into n into p is equal to log m plus log n plus log p. So therefore, log of x plus 3 whole square into x plus 4 raised to power 3 into x plus 5 raised to power 4 is equal to x plus 3 plus 4. Now, differentiate both sides with respect to x. We get into derivative of y with respect to x that is dy by dx is equal to 2 over into derivative of x plus 3 that is into 1 plus x is equal to y into 2 over x plus 3. Substitute the value of y here dx is equal to now y is x plus 3 whole square into x plus 4 whole cube into x plus 5 raised to power 4 into plus 3 and this that is 2 over x plus 3 plus 3 over x plus 4 plus 4 over x plus 5. And let us solve it separately. We have this portion and solve it separately. We have 2 over x plus 3 plus 3 over x plus 4 plus 5 is equal to x that is 9x, that is 8x, that is 7x, 70x, 33. Upon for dy by dx is equal to raised to power 4 is equal to the solution we get raised to power 2 into raised to power 3 into 9 and function is n 33. So, this is our answer. The question is clear to you. Bye and take care.
