May 29, 2021 ... I have seen in a video, the log2(1+x)=x approximation for a very small x (here between 0 and 1). The thing is, a correction term is added : u. x1, x = 81. 3. Set up equation. 0 = log2(3x – 4) + 1,. -1 = log2(3x – 4). Use log2a = b→ a = 2b. 2-1 = 3x – 4, ½ = 3x – 4. Solve x = 3/2. 4. Use laws of logs. log2 (x-1)+ log2 (x+3)=3 log2 ((x-1)(x+3)) = 3 (x-1)(x+3) = 2^3 x^2+3x-x-3 = 8 x^2+2x-3 = 8 x^2+2x-11 = 0 applying the "quadratic formula" we get: x = {2.46, - ... 3) The answers will be posted in Canvas within one day after the exam. ...
