Rewrite a logarithmic equation in exponential form
Problem
Rewrite \(y~=~\log_2(x)\) in exponential form.
Big Picture
What this problem is really about
A logarithm is a statement about an exponent, so preserve the three roles when rewriting it. The logarithmic base stays the exponential base, the value of the logarithm becomes the exponent, and the argument becomes the result of the power. Reading those roles aloud is a reliable way to prevent swaps.
