Step 1 :Given the equation \(\log _{2}(x+1)-\log _{2} x=2\)
Step 2 :Using the properties of logarithms, we can combine the two logarithms on the left side of the equation to get \(\log _{2}\frac{x+1}{x}=2\)
Step 3 :By definition of logarithms, we can rewrite the equation as \(\frac{x+1}{x}=2^2\)
Step 4 :Simplifying the right side of the equation gives us \(\frac{x+1}{x}=4\)
Step 5 :Multiplying both sides of the equation by \(x\) to get rid of the fraction gives us \(x+1=4x\)
Step 6 :Subtracting \(x\) from both sides to isolate \(x\) on one side of the equation gives us \(1=3x\)
Step 7 :Finally, dividing both sides by \(3\) to solve for \(x\) gives us \(x=\frac{1}{3}\)
Step 8 :The solution to the equation is \(\boxed{\frac{1}{3}}\)
