Exponential Equations
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...

Logarithmic Equations and Systems
Logarithmic Equations and Systems A logarithmic equation is an equation that has an unknown factor in the argument of a logarithm. In reality, the resolution is reduced to the resolution of equations of the same type as the expressions in the arguments (quadratic equations, cubic equations, irrational equations...). Before starting the exercises, let's remember the logarithmic properties: Logarithm of a product: Logarithm of a quotient: Logarithm of a power: Change of base: Use...
