Question

I need help in number 13

Answer 1

Answer:

$\huge\boxed{-0.602}$

Step-by-step explanation:

$\displaystyle log (\frac{1}{4} )\\\\We \ know \ that :\\\\log (\frac{x}{y} ) = log x - log y\\\\Applying \ the \ above \ rule\\\\= log 1 - log 4\\\\Given \ that \ log \ 1 = 0 , log \ 4 = 0.602\\\\= 0 - 0.602\\\\= -0.602\\\\\rule[225]{225}{2}$

Hope this helped!
