Best ResponseYou've already chosen the best response.1Now that's one that confuses me, too, lol x_x Not even sure what you're supposed to do with it. Curious to see what other people say.

Best ResponseYou've already chosen the best response.0Can We Use Lhospitals Rule ?

Best ResponseYou've already chosen the best response.1Don't even know how to do that :P But the only thing I would be able to do is recognize that the function is x^(3.25) and go from there. But that;d be cheating I think. And nah, lhopitals rule is above his class.

Best ResponseYou've already chosen the best response.1L'hopitals rule is a calc II thing, so not much to worry about for yourself, lol.

Best ResponseYou've already chosen the best response.0differentiate both numerator n denominator with respect to h u got ur answer n put h =0

Best ResponseYou've already chosen the best response.1I was thinking the same as Psyman mentioned that the original function is y=x^(3.25) dy/dx=3.25x^(2.25) i guess in order to evaluate the limit Binomial expansion is required

Best ResponseYou've already chosen the best response.0simple l hopital rule wud do in this case

Best ResponseYou've already chosen the best response.1I was thinking the expansion wasn't what the question really wanted, though.

Best ResponseYou've already chosen the best response.0\[\frac{ dx^p }{ dx }=\lim_{h \rightarrow 0}\frac{ (x+h)^px^p }{ h }=px^{p1}\] And in this case p=3.125

Best ResponseYou've already chosen the best response.0Then the solution:\[3.25x^{4.25}\]

Best ResponseYou've already chosen the best response.1this is as mentioned above the derivative of the function \[\Large y=x^{3.25}\] using the power rule of derivative which states if \[\Large y=x^n\] \[\Large \frac{dy}{dx}=nx^{n1}\] here n=3.25 just appply the power rule formula \[\Large \frac{dy}{dx}=3.25x^{(3.251)}\] \[\Huge \frac{dy}{dx}=3.25x^{4.25}\]

Best ResponseYou've already chosen the best response.1Yeah, more of just a knowledge of what the power rule for a derivative is and where within that difference quotient the original function actually is. In the end, it's the start of getting used to nx^(n1) for derivatives :P
