y=(x+1)^⅔·(x-5)²怎么求导
3个回答
展开全部
y = (x+1)^(⅔)×(x-5)²
y'= (2/3)(x+1)^(⅔-1)×(x-5)²+(x+1)^(⅔)×2(x-5)(x-5)'
y'= (2/3)(x+1)^(-1/3)(x-5)²+2(x+1)^(⅔)(x-5)
y'= (2/3)(x+1)^(⅔-1)×(x-5)²+(x+1)^(⅔)×2(x-5)(x-5)'
y'= (2/3)(x+1)^(-1/3)(x-5)²+2(x+1)^(⅔)(x-5)

y = (x+1)^(⅔) · (x-5)²
lny = (2/3)ln(x+1) + 2ln(x-5)
y'/y = (2/3)/(x+1) + 2/(x-5)
y' = (x+1)^(⅔) · (x-5)² [(2/3)/(x+1) + 2/(x-5)]
lny = (2/3)ln(x+1) + 2ln(x-5)
y'/y = (2/3)/(x+1) + 2/(x-5)
y' = (x+1)^(⅔) · (x-5)² [(2/3)/(x+1) + 2/(x-5)]
