Answer 2

Answer:

-1

Step-by-step explanation:

Properties used

$log_{a^n}{b}=1/n*log_{a}{b}$

$log_{a}{a}=1$

Solution:

by using the above properties we can write the equation as

$log_{2}log_{25}{5}\\=log_{2}log_{5^2}{5}\\=log_{2}*1/2*log_{5}{5}\\=log_{2}*1/2*1\\=log_{2}{2^-^1$

$=-1log_{2}{2}\\=-1$

Hope this helps.
