Đạo hàm của hàm số y=3^x-1/5^x

$A. y^{\text{'}}={\left(\frac{3}{5}\right)}^x\ln \frac{3}{5}+{\left(\frac{1}{5}\right)}^x\ln 5$

$B. y^{\text{'}}=x{\left(\frac{3}{5}\right)}^{x-1}-x{\left(\frac{1}{5}\right)}^{x-1}$

$C. y^{\text{'}}={\left(\frac{3}{5}\right)}^x\ln \frac{3}{5}-{\left(\frac{1}{5}\right)}^x\ln 5$

$D. y^{\text{'}}=x{\left(\frac{3}{5}\right)}^{x-1}+x{\left(\frac{1}{5}\right)}^{x-1}$
