Evaluate log base 3 of 59049
log3(59049)log3(59049)
Step 1
Rewrite as an equation.
log3(59049)=x
Step 2
Rewrite log3(59049)=x in exponential form using the definition of a logarithm. If x and b are positive real numbers and b does not equal 1, then logb(x)=y is equivalent to by=x.
3x=59049
Step 3
Create equivalent expressions in the equation that all have equal bases.
3x=310
Step 4
Since the bases are the same, the two expressions are only equal if the exponents are also equal.
x=10
Step 5
The variable x is equal to 10.
