Question:

Match List I with List II

LIST I LIST II
A. $\frac{d}{dx}(a^x)$ I. 1
B. $\frac{d}{dx}(x^e)$ II. 2x
C. $\frac{d}{dx}(e^{log_ex})$ III. $a^xlog_ea$
D. $\frac{d}{dx}(e^{2log_ex})$ IV. $ex^{e-1}$

Choose the correct answer from the options given below :

Options:

A-III, B-I, C-II, D-IV

A-III, B-IV, C-I, D-II

A-IV, B-III, C-I, D-II

A-II, B-III, C-IV, D-I

Correct Answer:

A-III, B-IV, C-I, D-II

Explanation:

The correct answer is Option (2) → A-III, B-IV, C-I, D-II

(A) $\frac{d}{dx}(a^x)=a^x\log_ea$ (III)

(B) $\frac{d}{dx}(x^e)=ex^{e-1}$ (IV)

(C) $\frac{d}{dx}(e^{\log_ex})=e^{log_ex}×\frac{1}{x}=x×\frac{1}{x}=1$ (I)

(D) $\frac{d}{dx}(e^{2\log_ex})=e^{2\log_ex}×\frac{2}{x}=x^2×\frac{2}{x}=2x$ (II)
