We are given the function:

\[
g(t) = \frac{1}{(2t + 1)^2}
\]

To find the derivative \( g'(t) \), we can use the **chain rule** combined with the **power rule**. Here is the step-by-step process:

### Step 1: Rewrite the function
We can rewrite the function in a more convenient form for differentiation:

\[
g(t) = (2t + 1)^{-2}
\]

### Step 2: Apply the chain rule
Using the chain rule, the derivative of \( (2t + 1)^{-2} \) with respect to \( t \) is:

\[
g'(t) = -2(2t + 1)^{-3} \cdot \frac{d}{dt}(2t + 1)
\]

### Step 3: Differentiate the inner function
The derivative of \( 2t + 1 \) with respect to \( t \) is simply \( 2 \). So the derivative becomes:

\[
g'(t) = -2(2t + 1)^{-3} \cdot 2
\]

### Step 4: Simplify the result
Simplifying the expression:

\[
g'(t) = -4(2t + 1)^{-3}
\]

Thus, the derivative of the given function is:

\[
g'(t) = \frac{-4}{(2t + 1)^3}
\]
