Question

What is the solution to the equation log 2 x – log 2 4 = 5 ?

Answer 1

what is
\[\log\bigg(\frac{A}{B}\bigg) \]
equal to?

Answer 2

I don;t know.

Answer 3

Ah,
Remember that logs are essentially exponents and follow their math rules.

Just like \[\frac{x^a}{x^n}=x^{a-n}\]
\[log\bigg( \frac{A}{B}\bigg) = log(A) - log(B)\]
and

\[log\bigg(AB\bigg) = log(A) + log(B)\]
