pictionaryoverlord Posted May 15, 2018 Report Share Posted May 15, 2018 Hey guys, so I'm having trouble differentiating (1/x^8)^1/5 and I've gotten to 1/x^(8/5) but I can't figure out how to apply the power rule to it. Please help? Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 16, 2018 Report Share Posted May 16, 2018 so d/dx (xn) is nxn-1.1/x^(8/5) is x-8/5. The derivative is thus -8/5 * x-13/5 Reply Link to post Share on other sites More sharing options...
