math please!

<p>i know this is totally the wrong place to post this but can somebody please help me with this one calc problem please? people don't seem to go on the calc threads as often but i really need help with this! thanks in advance!</p>

<p>Why can't i use the general power rule to integrate the integral of 1/ (square root of (4-x))dx....but i can use the general power rule to integrate the integral of 1/((x+1)^2)dx....</p>

<p>thanks so much again! i appreciate your help!</p>

<p>The second one you shouldn’t be able to either but I think it worked because the derivative of the inside thing is 1.</p>
