The correct Answer is:
To solve the integral \( \int (2x + 3)^5 \, dx \), we can use the method of substitution. Here are the steps: ### Step 1: Choose a substitution Let \( t = 2x + 3 \). ### Step 2: Differentiate the substitution Now, differentiate \( t \) with respect to \( x \): \[ \frac{dt}{dx} = 2 \implies dt = 2 \, dx \implies dx = \frac{dt}{2} \] ### Step 3: Substitute in the integral Substituting \( t \) and \( dx \) into the integral gives: \[ \int (2x + 3)^5 \, dx = \int t^5 \left(\frac{dt}{2}\right) \] This simplifies to: \[ \frac{1}{2} \int t^5 \, dt \] ### Step 4: Integrate Now, we can integrate \( t^5 \): \[ \int t^5 \, dt = \frac{t^6}{6} + C \] Thus, we have: \[ \frac{1}{2} \left( \frac{t^6}{6} + C \right) = \frac{t^6}{12} + \frac{C}{2} \] ### Step 5: Substitute back for \( t \) Now, substitute back \( t = 2x + 3 \): \[ \frac{(2x + 3)^6}{12} + C \] ### Final Answer Thus, the integral \( \int (2x + 3)^5 \, dx \) is: \[ \frac{(2x + 3)^6}{12} + C \]
