Question

write in exponential form: $\log _{2}8 = 3$

Explanation:

Step1: Recall log to exponent rule

For $\log_b a = c$, exponential form is $b^c = a$

Step2: Match values to the rule

Here, $b=2$, $c=3$, $a=8$. Substitute into $b^c = a$.
<Expression>
$2^3 = 8$
</Expression>

Answer:

A. $2^3=8$
