Question

what do you do, when there is a square root you're supposed to derive?

square root over 1+2x, How do you derive that without using the chain rule?

Answer 1

Hi,

\[\sqrt{2x+1}\]
is the same as:
\[(2x+1)^{1/2}\]

If you do not wish to use the chain rule, just go ahead and evaluate for \[2x ^{1/2}\] and \[1 ^{1/2}\] and then differentiate from there. This will work, however, chain rule will be the easiest. Hope that helps.

Answer 2

try u substitute
sub the inside and differentiate and then differentiate the outside
because without chain rule you answer is 1/2sqrt(2x+1)
