Sometimes we will be faced with logarithmic or exponential equations where the bases are not the same. Being able to change from one base to another will be helpful in these situations. Let’s have a look at the change of base formula for logarithmic functions. Change of base formula log b x = log a x log a b (1) Note: log t b = 1 log b t Let ...
The Change of Base formula is also useful for simplifying expressions involving logarithms of the same number to different bases, as the next 2 examples show. Example 6 Simplify 1 log4 5 + 1 log3 5. We know that 1 log4 5 = log5 4, and likewise 1 log3 5 = log5 3. Once everything is expressed to the same base we can use the properties of ...

The log base 2 to a number N in algebra is equal to the exponent value of 2 which gives the number N. The log base 2 is written in the logarithmic form as \(log_2N = k\), and the same is written in exponential form as 2 k = N. How Do You Solve Log Base 2? The log base 2 can be solved by transforming it into an exponential form.
Given that log 2 = x, log 3 = y and log 7 = z, express the following expressions in terms of x, y, and z. (1) log 12 (2) log 200. 14. (3) log (4) log 0:3. 3. (5) log 1:5 (6) log 10:5 6000. (7) log 15 (8) log. 7.
One of the common types of logarithms is Log Base 2 which uses 2 as the base. This logarithm is often used in computing and binary systems. For example, log base 2 of 8 is 3 because 2 3 =8. Below is the formula: Log 2 (8) = 3. I will show you ways to calculate Log Base 2 in Excel.
