### PRODUCT DESCRIPTION

This bundle has 10 self checking puzzle worksheets. Once the worksheets are completed, the answer to a riddle is revealed. The following are the contents of the worksheets:

1. Logarithms – Evaluate Using Change of Base
This worksheet evaluates logarithms which are not common logs. The base is either a number (other than 10) or a variable. The student is to solve for x, which is either the base, exponent or solution.

2. Logarithms - Product and Quotient Properties
This worksheet features two values given at the top of the page: Log base B of 3 and Log base B of 7. Twelve different problems are presented (such as log base B of (3/7)) and the students are to use the product, quotient or power property to expand the logarithm, then substitute in the values given at the top of the page. All solutions are decimals. My students were better with the product, quotient and power properties when they finished the worksheet.

3. Logarithms - Equations and Inequalities 1
This worksheet features logarithmic equations and inequalities which are begging to be solved. There are two types of logarithmic equations and inequalities: one using a logarithm on each side and one with a logarithm on only one side. The 'less than' inequalities will need to be solved with the domain in mind.

4. Logarithms - Equations & Inequalities 2
This worksheet includes exponential equations and inequalities. A common logarithm is used to solve each problem.

5. Logarithms - Solving Equations Using Properties 1
This worksheet requires the use of the product and quotient properties of logarithms to solve each equation. The log is on one side of the equation only. Some will require factoring a quadratic equation to solve, others will require pre-algebra skills to solve.

6. Logarithms - Solving Equations Using Properties 2
This worksheet is a little different than "Logarithms - Solving Equations Using Properties - 1." It requires the use of the product, quotient and power properties of logarithms to solve each equation. The log is on BOTH sides of the equation. Some will require factoring a quadratic equation to solve, others will require pre-algebra skills to solve.

7. Logarithms - Natural Logarithmic Equations
This worksheet has the students solving equations which either have a natural logarithm on exactly one side of the equal side or solving an equation which has the variable as the exponent of e. The student will need prior knowledge of the product, quotient and power properties of logarithms as they will need to use those properties to solve the equations.

8. Logarithms - Natural Logarithmic Equations Three Steps
This worksheet features two-step equations using the irrational number e. The variable is in the exponent, thus making it three steps. Problems similar to 2e^(4x) + 1 = 13 are on the worksheet.

9. Compounding Interest – Find Time or Principal
This worksheet uses either A=P(1+r/n)^(nt) or A=Pe^(rt) to solve word problems. The student must solve for time or principal. The student must not only decide which formula to use, but also decide to solve by using a logarithm or simply dividing.

10. Exponential Growth and Decay
This worksheet contains 10 word problems dealing with the equations y = a(1+r)^t and y = a(1-r)^t. The student will solve for t, so logarithms should be used to solve.
