Question

write in logarithmic form: $4^2 = 16$
$\log_2 4 = 16$
$\log_2 16 = 4$
$\log_4 16 = 2$

Explanation:

Step1: Recall exponent-logarithm conversion

For $b^y = x$, $\log_b x = y$

Step2: Match values to the formula

Here, $b=4$, $y=2$, $x=16$

Answer:

$\boldsymbol{\log_{4} 16 = 2}$ (Option: $\boldsymbol{\log_{4} 16 = 2}$)
