Logarithms tell the exponent or power a number must be raised.
The equation 3² = 9 can be written as log₃9=2.
What is Logarithm?
A log function is a way to find how much a number must be raised in order to get the desired number.
\(a^c =b\)
can be written as
\(\rm{log_ab=c\)
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Given to us
3^2 = 9
As we know about the logarithm, therefore, we can write the given equation as,
\(3^2 = 9\\\\log_39 = 2\)
Hence, the equation 3² = 9 can be written as log₃9=2.
