Exponential Equations An exponential equation is one that has exponential expressions, in other words, powers that have in their exponent expressions with the unknown factor x. For example: We will resolve some exponential equations without using logarithms. This method of resolution consists in reaching an equality of the exponentials with the same base in order to equal the exponents. Examples Example 1: Taking into account that we can write 16 as a power we can rewrite the equ...

Exponential and logarithmic functions are the most common types of functions which exist in the world around us. As a result there are many problems which may require the use of exponential or logarithmic equations in order to solve them. One example of this is the Richter scale, which measures the magnitude M of an earthquake according to the amplitude of its surface waves A Hence: M=log A+C where C =3.3+1.66 logD-logT is a constant which depends on the period of time that the waves are regi...
