Understanding Logarithms and Their Bases

The video tutorial introduces common logarithms, focusing on those with base 10. It explains that when discussing logarithms, the base is often omitted, implying base 10. The tutorial compares logarithms with different bases, such as 5, 8, and 10, and demonstrates how to calculate log base 10 using a calculator. The example given shows that log base 10 of 100 equals 2. The video emphasizes that future discussions will primarily involve base 10 logarithms.
