Question

Solve the following

Answer 1

Answer:

1. $log_{10} \: 35 - \: log_{10}17.5$

Answer: 0.331 \: aprox. [/tex]

2. $log_{3} \: 27 + 2 log_{3} \: 9 - log_{3} \: 54$

Answer: -9 log_{3}

Explanation:

$log_{10}35 - log_{10}17.5 \\ = log_ \frac{35}{17.5} \\ = log_{10}0.5 \\ = log_{5} - log_{10}10 \\ = log_{5 - 1} \\ = 0.669 - 1 \\ = 0.331 \: aprox.$
