Answer:

[tex]Log_5 12=1.54[/tex]

Step-by-step explanation:

We are given that

[tex]Log_5 12[/tex]

We have to find the value of given logarithms by using change-base formula

Base-change formula:

[tex]log_a b=\frac{Log_x b}{Log_x a}[/tex]

Where x=New base

Using the formula then, we get

[tex]Log_5 12=\frac{log_{10} 12}{log_{10} 5}[/tex]

Substitute the values [tex]log_{10}12=1.079, log_{10}5=0.699[/tex]

Then,we get

[tex]Log_5 12=\frac{1.079}{0.699}[/tex]

[tex]Log_5 12=1.54[/tex]
