WebSince logs cannot have zero or negative arguments, then the solution to the original equation cannot be x = −2. Then my solution is: x = 4 Keep in mind that you can always check your answers to any "solving" exercise by plugging those answers back into the original equation and checking that the solution "works". Web1) Expand \log_2 (3a) log2(3a). 2) Condense \log_5 (2y)+\log_5 (8) log5(2y)+log5(8). The quotient rule: \log_b\left (\dfrac {M} {N}\right)=\log_b (M)-\log_b (N) logb ( N M) = logb(M) − logb(N) This property says that the log of a quotient is the difference of the logs of the dividend and the divisor.
