  2. 1. Change-of-Base Law 2. Product Law 3. Quotient Law 4. Power Law Laws of logarithms

  3. The rule for the first law of logarithms is: If a, b and c are positive numbers and A not equal to 1, C not equal to 1, then Change-of-Base

  4. In this exercise you have to change the equation to the logarithms form and change the log to log 10 or lg then put lg 68 divide by lg 8 and sudtract with 4 and you will get the answer for this question. Exercise 1 • 1.

  5. In this exercise you have to put lg 5 divide by lg 3 and then you will get the answer for this Question (Be careful you have to use the calculator). Exercise 2 • 2.

  6. In this exercise the problems is in the multiple form so we have to divide the log again and you will see that every log cancel each other so the answer for this Question is 1. Exercise 3 • 3.

  7. Practice Exercise
