solve log(7x3)+2log(5)=2+log(x+3) I've attempted to do this question and I ended up with log(73)+log(5^2)log(x+3)=2 but I don't what to do next or whether I did something wrong.

Find the first and second derivative  simplify your answer. y=x/4x+1 I solved the first derivative and got 1/(4x+1)^2 Not sure if I did the first derivative right and not sure how to do the second derivative.

How do you get m=0? from taking the second derivative? does c=1? Can you check my work on how I get the derivative of R=M^2(c/2m/3) NEXT R=1/2(CM^2)1/3(M^3) NEXT dR/dM=CMM^2. I checked in the back, and that was the answer for the first part of the

I got this question, and found what I believe to be the solution, but want it confirmed. I started with: log[base5](2x+1) + log[base5](x1) = 1 And used the product law: log[base5]((2x+1)(x1)) = 1 log[base5](2x^2x1) = 1 Then I changed to exponential
