1.  Evaluate the expression.  Approximate your result to three decimal places.

 

            12.4^2.79

 

 

2.   Evaluate the expression.  Approximate your result to three decimal places.

 

            4^(3pi/2)

 

 

3.   Use the properties of logarithms to expand the expression as a sum, difference, and/or constant multiple of logarithms.

 

                        7x^2

            log     ---------

                        yz^3

 

 

4.    Condense the expression to the logarithm of a single quantity.

 

            Log (base 3) 13 + log (base 3) y

 

 

5.    Condense the expression to the logarithm of a single quantity.

 

            4 ln (x) – 4 (ln) y

 

 

6.   Solve the system by the method of substitution.

 

            x – y = -7

            4x + 5y = 8

 

 

 

 

 

 

 

7.   Solve the system by the method of substitution.

 

            y = x – 1

            y = (x -1) ^3

 

 

 

8.   Solve the system by the method of substitution.

 

            2x – y^2 = 0

            x – y =  4

 

 

9.   Solve the system by the method of elimination.

 

            2x + 3y = 17

            5x – 4y = -15

 

 

 

10.   Solve the system by the method of elimination.

 

            x – 2y + 3z = 11

            2x – z = 3

            3y + z = -8
