Algebra. Evaluate log base 3 of 9. log3 (9) log 3 (9) Rewrite as an equation. log3(9) = x log 3 (9) = x. Rewrite log3 (9) = x log 3 (9) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. 3x = 9 3 x = 9.
