Question

Express in exponential form. log2(x)=3

Answer 1

The relationship between logarithms and exponentials is that they are inverses of each other. That is, they are reflected about the line y = x.
In order to rewrite logarithms, we need to understand the basic fundamentals of them:
$log_ab = y$

This is essentially saying: "If we raise a to the y-th power, we get the answer to b".
Using this, we can say:
$log_2x = 3 \rightarrow 2^{3} = x$
