Answer:
![\log_{3}(25) = \frac{\log_{10}(25)}{\log_{10}(3)} = 2.93](https://tex.z-dn.net/?f=%5Clog_%7B3%7D%2825%29%20%3D%20%5Cfrac%7B%5Clog_%7B10%7D%2825%29%7D%7B%5Clog_%7B10%7D%283%29%7D%20%3D%202.93)
Step-by-step explanation:
We can use this expression to change the base of a logarithm from b to d.
![\log_{b}(x) = \frac{\log_{d}(x)}{\log_{d}(b)}](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28x%29%20%3D%20%5Cfrac%7B%5Clog_%7Bd%7D%28x%29%7D%7B%5Clog_%7Bd%7D%28b%29%7D)
So, to write
as base 10, we can use this formula.
![\log_{b}(x) = \frac{\log_{d}(x)}{\log_{d}(b)}](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28x%29%20%3D%20%5Cfrac%7B%5Clog_%7Bd%7D%28x%29%7D%7B%5Clog_%7Bd%7D%28b%29%7D)
![\log_{3}(25) = \frac{\log_{10}(25)}{\log_{10}(3)} = 2.93](https://tex.z-dn.net/?f=%5Clog_%7B3%7D%2825%29%20%3D%20%5Cfrac%7B%5Clog_%7B10%7D%2825%29%7D%7B%5Clog_%7B10%7D%283%29%7D%20%3D%202.93)
