1. Use the chain rule.

2. Use the product rule.

3. Use the quotient rule. You will need to use the chain rule at some point as well. - March 21st 2013, 03:35 PMPreston019Re: Differentiating expressions!! Please help :)
1. d/dx ln((x^3)+3 = (3x^2)/((x^3)+3)

2. d/dx (x^2)e^5x = 5(x^2)e^5x + (2x)e^5x

3. d/dx x/((1+x^2)^(1/2)) = [((1+x^2)^(1/2))(1) - ((2x)/(2((1+x^2)^(1/2))))]/(1+x^2)
