. The exponential function is an important mathematical function which is of the form. In other words, if \log (a)=\log (b) log(a) =log(b) then a a must equal b b \frac {x+1} {x-1}=1000 x −1x +1 = 1000 6 Multiply both sides of the equation by x-1 x−1 x+1=1000\left (x-1\right) x+ 1 = 1000(x −1) 7 Solve the product 1000\left (x-1\right) 1000(x−1).
