List-I (Function) | List-II (Derivative w.r.t. x) | |
---|---|---|
(A) \( \frac{5^x}{\ln 5} \) | (I) \(5^x (\ln 5)^2\) | |
(B) \(\ln 5\) | (II) \(5^x \ln 5\) | |
(C) \(5^x \ln 5\) | (III) \(5^x\) | |
(D) \(5^x\) | (IV) 0 |
When calculating derivatives of exponential functions like \( 5^x \), remember that the derivative of \( a^x \) is \( a^x \ln a \). For constants such as \( \log_e 5 \), their derivative is zero. Applying the chain rule or constant rule will help simplify the calculations.
To match the functions in List-I with their derivatives in List-II, calculate the derivatives:
For (A) \(f(x) = \frac{5^x}{\log_e 5}\):
\(f'(x) = 5^x.\)
Thus, (A) matches with (III).
For (B) \(f(x) = \log_e 5\):
\(f'(x) = 0.\)
Thus, (B) matches with (IV).
For (C) \(f(x) = 5^x \log_e 5\):
\(f'(x) = 5^x \log_e 5.\)
Thus, (C) matches with (II).
For (D) \(f(x) = 5^x\):
\(f'(x) = 5^x (\log_e 5)^2.\)
Thus, (D) matches with (I).
Final Matching: (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
To match the functions in List-I with their derivatives in List-II, we need to calculate the derivatives of each function:
For (A) \( f(x) = \frac{5^x}{\log_e 5} \):
The derivative of \( f(x) \) is:
\( f'(x) = 5^x \),
Thus, (A) matches with (III).
For (B) \( f(x) = \log_e 5 \):
The derivative of \( f(x) \) is:
\( f'(x) = 0 \),
Thus, (B) matches with (IV).
For (C) \( f(x) = 5^x \log_e 5 \):
The derivative of \( f(x) \) is:
\( f'(x) = 5^x \log_e 5 \),
Thus, (C) matches with (II).
For (D) \( f(x) = 5^x \):
The derivative of \( f(x) \) is:
\( f'(x) = 5^x (\log_e 5)^2 \),
Thus, (D) matches with (I).
Final Matching:
(A) - (III), (B) - (IV), (C) - (II), (D) - (I)
