Given the equation: 2x=16 or 2x−16=0 or 2x=16 or 2x=16 - this is the simplest exponential equation Do replacement v=2x we get v−16=0 or v−16=0 Move free summands (without v) from left part to right part, we given: v=16 We get the answer: v = 16 do backward replacement 2x=v or x=log(2)log(v) The final answer x1=log(2)log(16)=4
