# Project #10533 - math

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
