Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to Tan's book, the required text for the course. You should write up solutions neatly to all problems, making sure to SHOW ALL YOUR WORK. A nonempty subset will be graded. You are strongly encouraged to work on these problems with other classmates, although the solutions you turn in should be your own work.

**Section 5.1**

Problems: 2, 5, 11, 15, 20, 23, 26, 32

**Hint:** Be sure to do both parts **a** and **b** for problems
2, 5, 11 and 15. On problem 26, try setting y = 2^x and substituting into
the equation given. You will get a quadratic equation in y which is solvable
by factoring. After finding the y-value(s) which satisfy this equation, go back and solve for x.

**Section 5.2**

Problems: 11, 14, 17, 21, 31, 35, 40

**Section 5.3**

Problems: 2, 3, 9, 20, 22, 23
