Solve following 4e1+3 x - 9e5-2 x = 0 .
Solution
Here the first step is to get one exponential on every side & then we'll divide both sides by one of them (that doesn't matter for the most part) therefore we'll have a quotient of two exponentials. Then the quotient can be simplified & finally we'll get both coefficients on the other side.
Doing all of this gives,
4e1+3 x = 9e5-2 x
e1+3 x / e5-2 x = 9/4
e1+3 x-(5-2 x) = 9/4
e5 x-4 = 9/4
Note as well that while we said that it doesn't actually matter which exponential we divide out by doing it the way we did now we'll ignore a negative coefficient on the x. Not major issue, however those minus signs on coefficients are actually easy to lose on occasion.
Now this is in a form that we can deal with so here's the rest of the solution.
5x - 4 = ln ( 9/4 )
5x = 4 + ln ( 9/4 )
x = 1/5 (4 ( ln ( 9/4 )) = 0.9621860432
This equation contain single solution of x = 0.9622 .
Now let's see some equations which involve logarithms. The main property that we'll be using to solve these kinds of equations is,
blogbx = x
