1.1 Exponential Equations An exponential equation is an equation like 2x = 16 or 10x = 3.267. The first equation has answer x = 4, but the second equation is much harder to solve. An exponential equation has the general form ax = b, where the base a and the number b are known and we wish to find find the unknown index x. These type of equations arise frequently in growth and decay problems ...
