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...
Lord of the Pickles Posted May 18, 2018 Report Share Posted May 18, 2018 remember that 1/x = x^-1. So 1/x^(8/5) would be equal to x^(-8/5). You can then use the power rule to differentiate like normal -8/5x^((-8/5) - 1) = (-8/5)x^(-13/5) If you want to take the negative out of the exponent: -8/(5x^13/5) (It looks clearer handwritten).
