12 Maths Chapter 5 Exercise 5.4 solutions in English & Hindi medium is given below for new academic session 2020-2021. In this exercise, we have learned about the derivatives of exponential and logarithm functions. इससे पहले हम बहुपद फलन, त्रिकोणमितीय फलन तथा परिमेय फलन आदि के अवकलज प्राप्त करना सीखा है। इस प्रशनावली में चरघातांकी तथा लघुगुणकीय फलनों के अवकलज ज्ञात करना सींखेंगे। Ask your query related to NCERT Solutions, Offline Apps, NCERT Books, CBSE or NIOS board, etc., through discussion forum.




About 12 Maths Exercise 5.4

So far we have done the derivatives polynomials, rational numbers, trigonometric functions and tested the differentiability of modulus function, greatest integer function, etc. Now we have to deal with exponential and logarithm functions. So, we must know about the properties of log, which will be very useful for Exercise 5.5.
If any function is given as the sum of two exponential function, we can’t take log directly (This is the common mistake done by most of the students). We should differentiate the two functions separately and combine them to get the final answer.



Properties of log functions

1. log ab = log a = log b
2. log a/b = log a – log b
3. lag a^b = b log a
log function में योग का कोई नियम नहीं होता है। अर्थात log (a + b) ≠ log a + log b, इसलिए यदि कोई फलन, दो चरघातांकी फलनों के योग के रूप में है तो उन्हें अलग – अलग किसी चर में मान कर उसका अवकलज करें और फिर दोनों हलों को जोड़ दें।
