Some students like to think of the above simplification as meaning that the b and the log-base-b "cancel out". EX: log (2 6) = 6 × log (2) = 1.7, we have: 2^{1. x 2-3x-4 = 0. Quy tắc tích số có thể được sử dụng để tính toán nhân nhanh bằng phép cộng. We can change the base of any logarithm by using the following rule: log b ( a) = log x ( a) log x ( b) Notes: When using this property, you can choose to change the logarithm to any base x. If x x and b b are positive real numbers and b ≠ 1 b ≠ 1, then logb(x) = y log b ( x) = y is equivalent to by = x b y = x.
