hi, how do u solve this problem using limit notation. I tried it but go stuck at the last part. find f'(x) for f(x)=Sqrt2x-1 using F(x+h)-f(a)/h i got to the end and i got 1/Sqrt2x-1 -sqrt2x-1. i don't know wht u do next?
Can somebody explain how to do this? I am stuck. I've tried solving for H+ concentration. I got .00024M and subtracted it from [OH-]. Then I solved for pOH and used that to get pH but still got the wrong answer. Somone plz explain
