Question

Please, I desperately need help with logarithms question D: Refer to image. Please help with just part a) at least. I will use the method you teach to do the other parts myself.

Answer 1

You can rewrite the equation log 25 - log 3a
= log5^2-log3a

From given information log 3=0.477
a=3^0.477

Try it from here

Answer 2

I'm not sure how to continue...

Answer 3

(a)
\[\frac{\log_{a} 25}{\log_{a} 3a}=\frac{2\log_{a} 5}{\log_{a} 3+\log_{a} a}\]
\[\log_{a} a=1\]
Now you just need to substitute the given values into the right hand side of the first equation above to find the answer. Can you do that?

Answer 4

\[\frac{2\times 0.699}{0.477+1}=You\ can\ calculate\]
