if y=(√3x^24), then dy = a. 6x(√3x^24)dx b. (3x)/(√3x^24)dx c. (6x)/(√3x^24) d.
2(√3x^24)/(3x)dx
there is an E choice but it cut off, is it E??...

Best ResponseYou've already chosen the best response.1Dude, we're not here to do problems for you. I'm here to help work through them. Your question should be: Help me find the differential dy given \[y=\sqrt x^24\]

Best ResponseYou've already chosen the best response.1So do you need help differentiating or not? Also, your function's not clear. Is this it? \[y=\sqrt{3x^24}\]

Best ResponseYou've already chosen the best response.1When dealing with chain rule, it often helps to make your own functions up. Let: \[f(x) = \sqrt x\]\[g(x)=3x^24\]Then,\[y=f(g(x))\]Well let's take d/dx of both sides.\[\frac{dy}{dx}=f'(g(x))g'(x)\]Now, all you have to do is multiply by dx on both sides and replace all the f's and g's with their actual values. \[\frac{dy}{dx}dx=f'(g(x))g'(x)dx\]\[dy = f'(g(x))g'(x)dx\]
