none
The Attempt at a Solution
would i start of like this?
e^(2-3x)>4
ln(2-3x)>ln4
if so how do i continue?

What language is this?lasner12 said:no ide bro... sorry
A logarithmic equation is an equation that contains logarithmic functions, which are the inverse of exponential functions. In other words, a logarithmic equation is used to solve for the power or exponent that a base number needs to be raised to in order to equal a given number.
To solve a logarithmic equation, you need to isolate the logarithmic function on one side of the equation and the numerical value on the other side. Then, you can use the properties of logarithms to simplify the equation and solve for the variable.
The three main properties of logarithms are:
The two most common bases for logarithmic equations are base 10 (log10) and base e (ln). Base 10 is typically used in everyday calculations, while base e is used in more advanced mathematical equations.
Yes, logarithmic equations have many applications in real-life situations, such as measuring the magnitude of earthquakes, measuring sound intensity, and calculating the pH level of a solution. They are also used in finance and economics to calculate compound interest and growth rates.
