I have like 5 homework problems that are just killing me. I need some explanations on how to do them pl0z.

1)Find the derivative of this function:
F(x)=(4x-x^2)^100
2)Find the first and second derivatives of the function:
y=e^(e^x)
3)Find dy/dx by implicit differentiation:
sqroot(x+y)=1+(x^2)(y^2)
4)Differentiate the function :
f(x)=ln(5th root of x)
5)Use logarithmic differentiation to find the derivative of the function:
y=sinx^(lnx)
