Math Problem Statement
if log10(5)=x, find the value of log2(5) in terms of x
Solution
We are given that:
We need to find in terms of . We can use the change of base formula for logarithms, which states:
In our case, we want to convert into terms of base 10 logarithms. So, we can express as:
But we know from the problem that , so we substitute this:
Thus, the value of in terms of is:
