Problem

If y=exlog⁡xx2y = \frac{e^x \log x}{x^2} , then dydx=\frac{dy}{dx} = (a) ex[1+(x+2)log⁡x]x3\frac{e^x [1 + (x + 2) \log x]}{x^3} (b) ex[1−(x−2)log⁡x]x4\frac{e^x [1 - (x - 2) \log x]}{x^4} (c) ex[1−(x−2)log⁡x]x3\frac{e^x [1 - (x - 2) \log x]}{x^3} (d) ex[1+(x−2)log⁡x]x3\frac{e^x [1 + (x - 2) \log x]}{x^3}
