    chain rule

    Is the derivative of q(x)=x(2x+3)^{3/2}

    q'(x)=(5x+3)\sqrt{2x+3} ?

    In case you guys haven't noticed yet, I'm checking my homework. So, if the answer is wrong, just tell me that it's wrong, or give me a hint. I want to do the actual problems by myself.

    Yes. Factorise the output from here to see that: differentiate x (2x + 3)^(3/2) - Wolfram|Alpha
