Question

Express 4^2 =16 in logarithmic form

Answer 1

For this case we have that by defining logarithm properties, it is true that:

$log_ {b} (a) = c$ is equivalent to $b ^ c = a$

So, if we have the following expression:

$4 ^ 2 = 16\\b = 4\\c = 2\\a = 16$

We rewrite it as:

$log_ {4} (16) = 2$

Answer:

The equivalent expression is:

$log_ {4} (16) = 2$
