log2 x=4

To solve the equation \( \log_2 x = 4 \), you can rewrite it in exponential form. The equation states that \( x \) is the number you get when \( 2 \) is raised to the power of \( 4 \).

So, we can rewrite the equation as:

\[ x = 2^4 \]

Calculating \( 2^4 \):

\[ 2^4 = 16 \]

Thus, the solution is:

\[ x = 16 \]
