Срочно нужна помощь y=√2x-1/3 + ln 2x+3/5

Answer 1

$y=\sqrt{\frac{2x-1}3}+\ln\frac{2x+3}5\\\\y''=\frac1{2\sqrt{\frac{2x-1}3}}\cdot\left(\frac{2x-1}3\right)'+\frac1{\frac{2x+3}5}\cdot\left(\frac{2x+3}5\right)'=\\\\=\frac12\sqrt{\frac3{2x-1}}\cdot\frac23+\frac5{2x+3}\cdot\frac25=\frac13\sqrt{\frac3{2x-1}}+\frac2{2x+3}$
