find expressions for dy/du, and du/dx, then use the chain rule to find dy/du in terms of x.

y=e^5u u=x^3 + 1

1. dy/du= 2. du/dx= 3.dy/dx=

two others:

4. find dy/dt

y=6e^2tln(squareroot3t)

5. Dxf(x)

f(x)=x^2 +2/x-1

sorry i meant to have it say: find Dxf(x)= (x^2 +2)/ (x-1)

ok, since i'm getting no response, i'll assume that you mean the derivative with respect to x when you say Dx, so here

sorry i stepped away from the computer but yes thats what i meant by it. thanks for the help i appreciate it.
