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...
