What is d/dx [ln(6x+1)]?
d/dx [ln(6x+1)] क्या है?
Show answer and explanation
Correct Answer
B. 6 / (6x+1)
ExplanationStep 1: Identify the concept: logarithmic derivative. Step 2: The derivative of ln u is u'/u. Here u'=6, so the answer is 6/(6x+1). Step 3: Exam tip: In log derivative, numerator is the inner derivative.
Step 1: अवधारणा logarithmic derivative है। Step 2: ln u का derivative u'/u है। यहाँ u'=6, इसलिए answer 6/(6x+1)। Step 3: याद रखें: ln derivative में numerator inner derivative होता है।
