Only certain types of exponential equations can be solved using algebra. We will study the following types:

• The unknown, x, occurs only once.Example Go to topic • The equation is of the form a·b=^{ x}c·d.^{ x}Example Go to topic • The only exponential in the equation is b, and it occurs several times.^{ x}Example Go to topic • The equation contains the exponentials b,^{ x}b^{ 2 x},b^{ 3 x}, etc.Example Go to topic
