Precalculus - Logarithms and Laws of Logarithms

Step-by-step tutorial. This video shows the method of solving logarithms related questions. What kind of questions should apply what kind of laws.

Laws of Logarithms
1. If y=a^x then x=log_a⁡y
2. log_x⁡〖a^b 〗=b log_x⁡a
3. log_x⁡〖ab=log_x⁡a 〗+log_x⁡b
4. log_x⁡〖a/b=log_x⁡a 〗-log_x⁡b
5. log_b⁡a=log_x⁡a/log_x⁡b =1/log_a⁡b
6. log_a⁡a=1
7. log_e⁡a=ln⁡a
8. log⁡1=0
