B. $\frac{d}{dx}(x^a)$ II. $x^x(1+log_ex)$
C. $\frac{d}{dx}(a^a)$ III. $ax^{a-1}$
D. $\frac{d}{dx}(x^x)$ IV. $a^xlog_ea$

Choose the correct answer from the options given below :

Options:

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

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

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

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

Correct Answer:

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

Explanation:

The correct answer is Option (4) → A-IV, B-III, C-I, D-II

(A) $\frac{d}{dx}(a^x)=a^x\log a$ (IV)

(B) $\frac{d}{dx}(x^a)=ax^{a-1}$ (III)

(C) $\frac{d}{dx}(a^a)=0$ (I)

(D) $\frac{d}{dx}(x^x)=x^x(1+\log x)$ (II)
