Looking at it another way, the expression 2 log 2 (9) = y means "log 2 (y) = log 2 (9)", which is the equivalent logarithmic statement, so y = 9. 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. We ask, "To what exponent must 2 2 be raised in order to get 8?" Because we already know 2 3 = 8, 2 3 = 8, it follows that log 2 8 = 3. Write the factored form using these integers. Theorem 6.2. If x x and b b are positive real numbers and b ≠ 1 b ≠ 1, then logb(x) = y log b ( x) = y is
