What is the derivative of $q\left(x\right)=\frac{25}{3+5^{-x}}$?

$q^{\prime }\left(x\right)=-\frac{\ln \left(5\right)\cdot 5^{-x}}{{(3+5^{-x})}^2}$

$q^{\prime }\left(x\right)=\frac{\ln \left(5\right)\cdot 5^{-x}}{{(3+5^{-x})}^2}$

$q^{\prime }\left(x\right)=-\frac{25\ln \left(5\right)\cdot 5^{-x}}{{(3+5^{-x})}^2}$

$q^{\prime }\left(x\right)=\frac{25\ln \left(5\right)\cdot 5^{-x}}{{(3+5^{-x})}^2}$
