Question:

$\frac{d}{dx}(e^{2\log_ex^3})$ equals

Options:

$30x^4$

$6x^5$

$5x^6$

$3x^2$

Correct Answer:

$6x^5$

Explanation:

The correct answer is Option (2) → $6x^5$

Given: $y = e^{2 \ln x^3}$

Simplify exponent: $2 \ln x^3 = 2 * 3 \ln x = 6 \ln x$

So $y = e^{6 \ln x} = x^6$

$\frac{dy}{dx} = 6x^5$

Answer: $6x^5$
