Answer :
Answer:
Option A
[tex]\log_3 81 =x[/tex]
Step-by-step explanation:
Use logarithmic rules:
- [tex]\log a^m = m\log a[/tex]
- [tex]\log_a b = \frac{\log a}{\log b}[/tex]
Given the equation:
[tex]81 = 3^x[/tex]
Taking both side logarithm function:
[tex]\log 81 = x\log 3[/tex]
Divide both sides by log 3 we have;
[tex]\frac{\log 81}{\log 3} = x[/tex]
Apply the logarithmic rules:
[tex]\log_3 81 =x[/tex]
therefore, [tex]81 = 3^x[/tex] as a logarithmic equation is [tex]\log_3 81 =x[/tex]
