Math Problem Statement

if log10(5)=x, find the value of log2(5) in terms of x

Solution

We are given that:

log10(5)=x\log_{10}(5) = x

We need to find log2(5)\log_2(5) in terms of xx. We can use the change of base formula for logarithms, which states:

logb(a)=logc(a)logc(b)\log_b(a) = \frac{\log_c(a)}{\log_c(b)}

In our case, we want to convert log2(5)\log_2(5) into terms of base 10 logarithms. So, we can express log2(5)\log_2(5) as:

log2(5)=log10(5)log10(2)\log_2(5) = \frac{\log_{10}(5)}{\log_{10}(2)}

But we know from the problem that log10(5)=x\log_{10}(5) = x, so we substitute this:

log2(5)=xlog10(2)\log_2(5) = \frac{x}{\log_{10}(2)}

Thus, the value of log2(5)\log_2(5) in terms of xx is:

xlog10(2)\boxed{\frac{x}{\log_{10}(2)}}
