Question

derivative of 3/(2t+1)​

Answer 1

-6(2t+1)^-2
Or
-6/(2t+1)^2

Answer 2

Answer:

$f(x) = \frac{3}{2t + 1} \\ \\ f(x) = 3( \frac{1}{2t + 1} ) \\ \\ f(x) =3( {2t + 1)}^{ - 1 } \\ \\ f'(x)\: = -3( {2t + 1)}^{ - 2} \frac{d}{dx} (2t + 1) \\ \\ \: \: \: \: \: \: \: \: \: \: \: = -\frac{3}{ {(2t + 1)}^{2} } (2) \\ \\ \: \: \: \: \: \: \: \: = -\frac{6}{ {(2t + 1)}^{2} }$
