1. 10lg: This is a logarithmic function based on 10, usually expressed as log 10. It represents the logarithm with the base of 10 in logarithmic operation. For example, 10lg 100=2, which means that the quadratic of 10 is equal to 100.
2.lg 10: This is a base-2 logarithmic function, usually expressed as log2. It represents the logarithm with base 2 in logarithmic operation. For example, lg 10=3.32 19, which means that the 3.32 19 power of 2 is equal to 10.
Therefore, the main difference between 10lg and lg 10 is that they use different cardinality, one is based on 10 and the other is based on 2.
