Question

use the change in base formula to evaluate the logarithm.
log2 5

Answer 1

Your calculator likely only has a base10 and baseE button to help you out.
So we need to change our base from 2 to one of those options so we can throw it into the calculator :)

Answer 2

Change of base formula:\[\Large\rm \log_b(a)=\frac{\log_{10}(a)}{\log_{10}(b)}\]

Answer 3

Applying the formula:\[\Large\rm \log_2(5)=\frac{\log_{10}(5)}{\log_{10}(2)}\]

Answer 4

so the answer would be @zepdrix

Answer 5

Yes, the answer would be zepdrix.

No, you need to use a calculator to finish up the problem.
