How do you find Log2?

To find Log2 of a number, you can use the change of base formula: Log2(x) = Log10(x) / Log10(2) or Log2(x) = Ln(x) / Ln(2), where Log10 is the logarithm to base 10 and Ln is the natural logarithm. You can also use a scientific calculator or logarithm tables that provide values for Log2 directly. Additionally, many programming languages have built-in functions to compute logarithms in various bases.
