## anonymous 5 years ago 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?

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.

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