Derivatives and Integrals of Exp and Log Functions

1. Find the derivatives for the following functions ("^" means "to the power of", sorry I can't do double exponents on my keyboard) :

a. f(X) = 100e10X

b. f(X) = e(10X-5)

c. f(X) = e^X3

d. f(X) = 2X2e^(1- X2)

e. f(X) = 5Xe(12- 2X)

f. f(X) = 100e^(X3 + X4)

g. f(X) = e^(200X - X2 + X100)

2. Find the derivatives for the following functions:

a. f(X) = ln250X

b. f(X) = ln(20X-20)

c. f(X) = ln(1- X2)

d. f(X) = ln(5X + X-1)

e. f(X) = Xln(12- 2X)

f. f(X) = 2Xln(X3 + X4)

g. f(X) = ln(200X - X2 + X100)

3. Find the indefinite intgrals for the following functions

a. f(X) = e6X
