Best ResponseYou've already chosen the best response.0\[\lim_{h \rightarrow 0}\frac{ \sqrt[3]{1695  8x^2} 7 }{ h } \]

Best ResponseYou've already chosen the best response.1same gimmick as with a square root, rationalize the numerator, but this time instead of using \[(ab)(a+b)=a^2b^2\] you have to use \[(ab)(a^2+ab+b^2)=a^3b^3\] so it is a pain in the arse

Best ResponseYou've already chosen the best response.0the answer is \[\frac{ 208 }{ 147 }\] i want to figure what to do to get it.

Best ResponseYou've already chosen the best response.1have fun but you can do it use \(a=\sqrt[3]{16958x^2}\) and \(b=7\)

Best ResponseYou've already chosen the best response.0\[\sqrt[3]{1695  8x^2} \] with 13 plugged in, which equals 7

Best ResponseYou've already chosen the best response.1ok then you can start with \[\frac{\sqrt[3]{16958(13+h)^2}7}{h}\]\]

Best ResponseYou've already chosen the best response.1you can leave it in this form, or you can write \[\sqrt[3]{343h^2208h}7\]

Best ResponseYou've already chosen the best response.1who gave you this problem? this really sucks unless you are supposed to use a shortcut, namely recognize this as the derivative and evaluate

Best ResponseYou've already chosen the best response.1do you know how to take a derivative? because then it it would be not so hard but if you do not, then there is a ton of work to be done

Best ResponseYou've already chosen the best response.0i do know, im not sure if it would give me the answer im supposed to get

Best ResponseYou've already chosen the best response.1this is the derivative of \[\sqrt[3]{16958x^2}\] evaluated at \(x=13\)

Best ResponseYou've already chosen the best response.1so if you can take the derivative, then plug in 13, you will get your answer

Best ResponseYou've already chosen the best response.1just to finish quick derivative is \[\frac{16x}{3(16958x^2)^{\frac{2}{3}}}\]

Best ResponseYou've already chosen the best response.1by the chain rule and power rule replace \(x\) by 13 and you should get your answer this is a much snappier way then doing it by hand
