Assertion (A):The derivative of (logx)x w.r.t x is (logx)x−1[1+logxlog(logx)]Reason (R): ddx{f(x)g(x)}=f(x)g(x) (g(x)f′(x)f(x)+g′(x)log(f(x)))
(a) Both Assertion (A) and Reason (R) are true and Reason (A) and Reason (R). For selecting the correct answer, use the following code :
(b) Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).
(c) Assertion (A) is true and Reason (R) is false.
(d) Assertion (A) is false and Reason (R) is true.
Assertion (A) Reason (R)√3 is an irrational number. The sum of a rational numberand an irrational number is anirrational number.The correct answer is: (a)/(b)/(c)/(d).
This question consists of two statements,namely,Assertion (A) and Reason (R).For selecting the correct answer,use the following code:
(a) Both Assertion (A) and Reason (R) are true and Reason (R) correct explanation of Assertion (A).
Assertion (A)Reason (R)If ABCD is a rhombus whose one Median of a triangle divides itangle is 60∘then the ratio of the into two triangles of equal area.lenghts of its diagonals is √3:1.
The correct answer is :(a) /(b)/(c)/(d).
