How to solve logarithm
WebA typical problem-solving strategy is using the change-of-base formula to make all the logarithms have the same base. This makes it much easier to apply other inequalities, such as AM-GM. Show that \log_n (n+1)>\log_ {n+1} (n+2) logn(n+1) > logn+1(n+2) for all integers n \geq 2 n ≥ 2. Using change of base, WebALWAYS check your solved values with the original logarithmic equation. Remember: It is OKAY for x to be 0 or negative. However, it is NOT ALLOWED to have a logarithm of a …

In this type, the variable you need to solve for is inside the log, with one log on one side of the equation and a constant on the other. Turn the variable inside the log into an exponential equation (which is all about the base, of course). For example, to solve log 3 x = –4, change it to the exponential equation 3 –4 = x, or 1/81 = x.
