Given the equation: 3x=−1 or 3x+1=0 or 3x=−1 or 3x=−1 - this is the simplest exponential equation Do replacement v=3x we get v+1=0 or v+1=0 Move free summands (without v) from left part to right part, we given: v=−1 We get the answer: v = -1 do backward replacement 3x=v or x=log(3)log(v) The final answer x1=log(3)log(−1)=log(3)iπ
