## How To Add Logs With Different Bases

#### How to Divide Exponents With Different Bases Sciencing

To get log base 10, we can use the change of base formula and note that $\displaystyle \log_{10}2 = \frac{\log 2}{\log 10}$. If you wish to find the logarithm with respect to a different base, you can select the function accordingly, or simply use the base change formula for logarithms.

#### How to multiply logs with different bases without using a

The number being multiplied is called the base. If b is the base and n is the exponent, we say “b to the power of n,” shown as b^n, which means b * b * b * b* b n times. For example “4 to the power of 3” means 4^3 = 4 * 4 * 4 = 64. There are rules for doing operations on exponential expressions. Dividing exponential expressions with different bases is allowed but poses unique

#### VB Helper HowTo Calculate logarithms in different bases

6/06/2009 · Best Answer: In general, you need convert one of the logarithms to the same base as the other one by using the relationship: log_a(b) * log_b(x) = log_a(x) or, written another way: log_b(x) = log_a(x)/log_a(b) where log_a and log_b mean the logarithms in base a and b, respectively. For instance: log_4(32
